Create a program that will accept 4 numbers. Get sum1 (sum of 1st and 2nd number) and sum2 (sum of 3rd and 4th number). Display both of the sums and which one is bigger.
Use cin to get input from user http://www.cplusplus.com/doc/tutorial/basic_io/
Use cout to display variables to the console.
You'll have something along this in your code
sum1 = n1 + n2;
sum2 = n3 + n4;
If you want people to help you, you have to try to help yourself first and post actual code you need help with.
#include "iostream"
#include "conio.h"
using namespace std;
int main()
{
float num1,num2,num3,num4,sum1,sum2;
cout<<"Enter 4 numbers";
cin>>num1>>num2>>num3>>num4;
sum1=num1+num2;
sum2=num3+num4;
cout<<"Sum of num1 and num2="<<sum1;
cout<<"\nSum of num3 and num4="<<sum2;
if (sum1>sum2)
cout<<"\nSum1 is bigger";
else
cout<<"\nSum2 is bigger";
getch();
return 0;
}
