We won't simply do your homework for you.
Show us how far you've got. Ask a question about something in your code you don't understand. You're going to have to do more than simply put the question up and hope we do it for you.
#include<iostream>
#include<math.h>
using namespace std ;
int a,b,c,d,num;
int maximum()
{
num=0;
if(a>b && a>c && a>d) { num==a;}
else if(b>a && b>c && b>d) { num==b;}
else if(c>a && c>b && c>d) { num==c;}
else { num==d;}
return num;
}
int main()
{
a=5 , b=7 , c=2 , d=3;
maximum();
cout<<"maximum number="<<num;
}
I tried that code but when I run it the max number appears to be zero
Well, you set n to zero on line 7 (n = 0;) and then you never change it so it's obviously still zero. Remember that == checks for equality. It does not set num to equal anything. Therefore, num==a; should be num = a; and then continue the same pattern on lines 9-11.
num==a;
This means "is the value of num
the same as the value of a
?" It does not change the value of num
.
Perhaps you're trying to set the value of num
? Did you mean num=a;
?
I found my mistake .. thank you all
