my program cannot compile.

#include <stdlib.h>

using namespace std;

int getmark();
char computeGrade();

int main()
{
    int mark = getmark();
	char Grade = computeGrade();
	cout<<Grade;
	
	
	system ("PAUSE");
	return 0;
}
int getmark()
{
 	int mark;
	cout<<"enter mark";
	cin>>mark;
	return mark;
}

char computeGrade(double marks)
{
	int mark;
	
	if ((mark>85) && (mark<100))
	   cout<<'A';
	else if((mark>75) && (mark<84))  
		 cout<<'B';

your functions doesnt have oppening and closing brackets.

[dharmendra1281]

sir on which line ..u min the curly braces ??

[fmehri76]

starting ones at 10 and 20, yes

don't know whether fmehri76 is just trolling...

the problem is that the function computeGrade() does not match the prototype on line 7.

By the way: the local variable on line 29 doesn't make sense. Replace double marks with int mark. Don't forget to adjust line 7. Then pass mark from line 11 to the function computeGrade(mark) on line 12

Why should I troll?! Im on a mobile phone so maybe it is rendered with some problem in my browser. Anyway I should check it in my pc. Sorry for giving wrong info.

hey,this would be the correct version of your program.

#include <iostream>
#include <stdlib.h>
using namespace std;

int getmark(void);
char computeGrade(int);

int main()
{
    int mark = getmark();
    char Grade = computeGrade(mark);
    cout<<"\n the grade is:";
    cout<<"\n"<<Grade;
	
	
	//system ("PAUSE");
	return 0;
}
int getmark()
{
 	int mark;
	cout<<"enter mark";
	cin>>mark;
	return mark;
}

char computeGrade(int mark)
{
	
	if ((mark>85) && (mark<100))
	   return 'A';
	else if((mark>75) && (mark<84))  
		return 'B';
    else if ((mark>65) && (mark<74))
		return 'C';  
}

also, you'll have to test the logic of your program.if you input mark as 85 you shall not get any grades output as you haven't checked for mark==85 anywhere in computegrade(), you're only checking for mark>85 and mark<84!@
