hi guys thanks for viewing and helping me out!!

here are the example what the things will looks like

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

Enter problems per set: 3 Set #1

What is the maximum number for this set? 100 45 + 21 = 66 correct 0 + 100 = 100 correct 54 + 23 = 67 incorrect Set #2 ---------- What is the maximum number for this set? 90 59 - 19 = 40 correct 19 - 84 = -29 incorrect 0 - 65 = -65 correct Set #3 ---------- What is the maximum number for this set? 20 0 * 18 = 0 correct 15 * 4 = 398 incorrect 8 * 17 = 873 incorrect Set#1: You got 2 correct out of 3 for 66.7% Set#2: You got 2 correct out of 3 for 66.7% Set#3: You got 1 correct out of 3 for 33.3% Overall you got 5 correct out of 9 for 55.6%

and we must have fixed int main which is

    int main()
    {
        <variable declarations>
        
        srand(static_cast<unsigned>(time(0)));    
        getProbsPerSet(<arguments>);  
        doOneSet(<no-more-than-3-arguments>);    
        doOneSet(<no-more-than-3-arguments>);
        doOneSet(<no-more-than-3-arguments>);
        printReport(<arguments>);
    }

so far i i've done with code with value of how many time it will repeated but i'm having some issue within set the randome number

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

void getProbsPerSet(int); // let user choose how many time probs

void doOneSet(char, int); // do one set of each problem
void doOneProblem(int&); // ask user the answer
void checkAnswer(int, int); // compare the answer if it's right
void generateOperands(char&); // declare which calculation it needs
void CalculateCorrectAnswer(int, int, char, int&); // Find correct answer

int main() {
	int probsPerSet;

	getProbsPerSet(probsPerSet); // calling out getProbsPerSet
	srand(static_cast<unsigned>(time(0))); // generate randome number
	doOneSet('+', probsPerSet); // calling out doOneSet with character +
	doOneSet('-', probsPerSet); // calling out doOneSet with character -
	doOneSet('*', probsPerSet); // calling out doOneSet with character *

	system("pause");
	return 0;
}

void   getProbsPerSet(int probs) {  // Many will have fixed value now
	int probsPerSet;
	cout << "Enter problems per set: ";
	cin >> probsPerSet; // return Many as typed value
	return probsPerSet;
}

void doOneSet(char Function, int Many) {  // catches int Many, char Function from follwing than do doOneset
	int i;

	if (Function == '+') { // if when char +
		for (i = 0; i < Many; i++) { // repeat with following Many
			int First, Second, Answer, Final;
			First = rand() % 101; // generate randome number under 100
			Second = rand() % 101; // generate randome number under 100
			cout << First;  // show first generated number
			generateOperands(Function); // show which function we are in
			cout << Second << " = ";  // show second function and =
			doOneProblem(Answer); // ask for user to put value as answer
			CalculateCorrectAnswer(First, Second, Function, Final); // get the correct answer
			checkAnswer(Answer, Final); // compare with use's answer and right answer and show if it's right or wrong
		}
	}
	if (Function == '-') {  // if when char -
		for (i = 0; i < Many; i++) { // repeat with following Many
			int First, Second, Answer, Final;
			First = rand() % 101; // generate randome number under 100
			Second = rand() % 101; // generate randome number under 100
			cout << First;  // show first generated number
			generateOperands(Function); // show which function we are in
			cout << Second << " = ";  // show second function and =
			doOneProblem(Answer); // ask for user to put value as answer
			CalculateCorrectAnswer(First, Second, Function, Final); // get the correct answer
			checkAnswer(Answer, Final); // compare with use's answer and right answer and show if it's right or wrong
		}
	}
	if (Function == '*') { // if when char *
		for (i = 0; i < Many; i++) {  // repeat with following Many
			int First, Second, Answer, Final;
			First = rand() % 101; // generate randome number under 100
			Second = rand() % 101; // generate randome number under 100
			cout << First;  // show first generated number
			generateOperands(Function); // show which function we are in
			cout << Second << " = ";  // show second function and =
			doOneProblem(Answer); // ask for user to put value as answer
			CalculateCorrectAnswer(First, Second, Function, Final); // get the correct answer
			checkAnswer(Answer, Final); // compare with use's answer and right answer and show if it's right or wrong
		}
	}
}

void doOneProblem(int& Ans) {
	cin >> Ans;
}

void CalculateCorrectAnswer(int X, int Y, char F, int& A) { // generate correct answer with givin value X,Y with given function F than return A
	if (F == '+') {
		A = X + Y;
	}
	if (F == '-') {
		A = X - Y;
	}
	if (F == '*') {
		A = X * Y;
	}
}

void checkAnswer(int Ans, int A) { //compare right answer than user's answer than answer if it's right or wrong
	if (Ans == A) {
		cout << "Correct" << endl;
	}
	else {
		cout << "Incorrect" << endl;
	}
}

void generateOperands(char& F) { // just little trick for generate fixed function
	cout << " " << F << " ";
}

how can i set the randome number in here? and where can i put the setmaxnumber?

please help me out!!!

Hi,
Can you show us your current program output?

[dragonk2]

sure

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

int main() {
	int probsPerSet;

	getProbsPerSet(probsPerSet);
	srand(static_cast<unsigned>(time(0)));
	doOneSet('+', probsPerSet);
	doOneSet('-', probsPerSet);
	doOneSet('*', probsPerSet);

	system("pause");
	return 0;
}

void   getProbsPerSet(int &Many) {
	cout << "Enter problems per set: ";
	cin >> Many;
}

void doOneSet(char Function, int Many) {
	int i;

	if (Function == '+') {
		for (i = 0; i < Many; i++) {

			doOneProblem(Answer);

		}
	}
	if (Function == '-') {

	}
	if (Function == '*') {

	}
	else {

	}
}

void generateOperands(char& F) {
	cout << " " << F << " ";
}

i'm still stuck in this

Well, the program output is not code. It is basically something like this :

What is the maximum number for this set? 100    
45 + 21 = 66
correct
0 + 100 = 100    
correct
54 + 23 = 67
incorrect

etc
