Bubble Sort?

[franci25]

So ive been working on this program for five hours now and i trying to sort this array of student names with their test scores. this is what i have

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <cstring>
using namespace std;

void getData(int size, int [], char [][6]);
void sortData(char [][6], int);

void main(){
int scores[5];
char students [5][6];
int size;

cout << "Enter size for arrays: ";
cin >> size;
getData(size,scores,students);

cout << "ARRAYS BEFORE SORTING" << endl;
for (int i = 0; i < 5; i++)
cout << students[i] << endl;
sortData(students, 5);

cout << "ARRAYS AFTER SORTING :" << endl;
for (int i = 0; i < 5; i++)
cout << students[i] << endl;
// end for





}

void getData(int size, int testScore[],char studentName[][6]) {

int index;

for (index = 0; index <= size -1; index++){
cout << "Enter " <<(index +1) << "th student name: "
<< ": ";
cin >> studentName[index];
cout << "Enter test score for " << studentName[index]
<< ": ";
cin >> testScore[index];

while (0 > testScore[index] || testScore[index] > 100){
cout << "Re-enter test score for " << studentName[index]
<< ": ";
cin >> testScore[index];

}// end while
}// end for

}

void sortData(int size, char studentName[][6]){
bool swap;
int temp[6];

do {
swap = false;
for (int count = 0; count < (size - 1); count++) {
if (strcmp(studentName[count], studentName[count+1]) > 0) {
strcpy_s(temp, studentName[count]);
strcpy_s(studentName[count], studentName[count+1]);
strcpy_s(studentName[count+1], temp);
swap = true;
} // end if
} // end for
} while (swap);

}

i get these errors:
error C2660: 'strcpy_s' : function does not take 2 arguments
error C2665: 'strcpy_s' : none of the 2 overloads could convert all the argument types c:\program files (x86)\microsoft visual studio 10.0\vc\include\string.h(104): could be 'errno_t strcpy_s<6>(char (&)[6],const char *) throw()' while trying to match the argument list '(char [6], int [6])'

please help!

strcpy_s(studentName[count], studentName[count+1]);
strcpy_s(studentName[count+1], temp);
swap = true;
} // end if
} // end for
} while (swap);

}

made a few changes. now i get these errors
error LNK2019: unresolved external symbol "void __cdecl sortData(char (* const)[6],int)" (?sortData@@YAXQAY05DH@Z) referenced in function _main
fatal error LNK1120: 1 unresolved externals

Can someone plz help me!

[Peter87]

In the definition of sortData you have switch the order of the parameters.

[franci25]

Thats not it

[Peter87]

Are you sure? Maybe I was unclear. If you compare the declaration

void sortData(char [][6], int);

to the definition

void sortData(int size, char studentName[][6])

you see that they are not the same.

[franci25]

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <cstring>
using namespace std;

void getData(int size, int [], char [][6]);
void sortData(char [][6], int[], int);
void printData(char [][6], int);

void main(){
int scores[5];
char students[5][6];
int size;

cout << "Enter size for arrays: ";
cin >> size;
getData(size,scores,students);

sortData(students, scores, 5);



}

void getData(int size, int testScore[],char studentName[][6]) {

int index;

for (index = 0; index <= size -1; index++){
cout << "Enter " <<(index +1) << "th student name: "
<< ": ";
cin >> studentName[index];
cout << "Enter test score for " << studentName[index]
<< ": ";
cin >> testScore[index];

while (0 > testScore[index] || testScore[index] > 100){
cout << "Re-enter test score for " << studentName[index]
<< ": ";
cin >> testScore[index];

}// end while
}// end for

}

void sortData(char studentName[][6],int testScore[],int size){
bool swap;
char temp[6];

do {
swap = false;
for (int count = 0; count < (size - 1); count++) {
if (strcmp(studentName[count], studentName[count+1]) > 0) {
strcpy_s(temp,6, studentName[count]);
strcpy_s(studentName[count],6, studentName[count+1]);
strcpy_s(studentName[count+1],6, temp);
swap = true;
} // end if
} // end for
} while (swap);

}

there we go i got it now.
do you think you can help me print the data by using a printData function

[Peter87]

I'm not going to write that function for you. If you have questions just post them here and someone will try to answer them.

[franci25]

alright ill try just to let u know iive been working on this since 3:30 and i still have a math exam to study for.

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <cstring>
using namespace std;

void getData(int size, int [], char [][6]);
void sortData(char [][6], int[], int);
void printData(char [][6], int[]);

void main(){
int scores[5];
char students[5][6];
int size;

cout << "Enter size for arrays: ";
cin >> size;
getData(size,scores,students);

sortData(students, scores, 5);

printData(students,scores);



}

void getData(int size, int testScore[],char studentName[][6]) {

int index;

for (index = 0; index <= size -1; index++){
cout << "Enter " <<(index +1) << "th student name: "
<< ": ";
cin >> studentName[index];
cout << "Enter test score for " << studentName[index]
<< ": ";
cin >> testScore[index];

while (0 > testScore[index] || testScore[index] > 100){
cout << "Re-enter test score for " << studentName[index]
<< ": ";
cin >> testScore[index];

}// end while
}// end for

}

void sortData(char studentName[][6],int testScore[],int size){
bool swap;
char temp[6];

do {
swap = false;
for (int count = 0; count < (size - 1); count++) {
if (strcmp(studentName[count], studentName[count+1]) > 0) {
strcpy_s(temp,6, studentName[count]);
strcpy_s(studentName[count],6, studentName[count+1]);
strcpy_s(studentName[count+1],6, temp);
swap = true;
} // end if
} // end for
} while (swap);


}

void printData(char studentName[][6], int testScores[]){

cout << "ARRAYS BEFORE SORTING" << endl;
for (int i = 0; i < 5; i++)
cout << studentName[i] << endl;

cout << "ARRAYS AFTER SORTING :" << endl;
for (int i = 0; i < 5; i++)
cout << studentName[i] << endl;

int ok;
cin >> ok;

}

i got this now

[franci25]

it only sorts the names idk how to sort the names with the scores.

[franci25]

void printData(char studentName[][6], int testScores[]){

cout << "ARRAYS BEFORE SORTING" << endl;
cout << "NAME" << "\t\t" << "SCORE" << endl;
for (int i = 0; i < 5; i++)
cout << studentName[i] << endl;
cout << static_cast<int>(testScores[i]) << endl;

cout << "ARRAYS AFTER SORTING :" << endl;
cout << "NAME" << "\t\t" << "SCORE" << endl;
for (int i = 0; i < 5; i++)
cout << studentName[i] << endl;

int ok;
cin >> ok;

}

still not working

int ok;
cin >> ok;

}

i got it but it sorts both of them. how do i sort only the last one?

[franci25]

i got it now. thanks for the hlep
