how can we code , like value of a+ value of b, if sum is 100 how can we put a if statement stating if value < 100 cout you tried hard...sometimes like that , I mean to say how can we combine a normal addition and subtraction with if statement.

Answer 1

i would do
int math;
cout what math? 1= Add, 2= Sub
cin math//User input

if(math ==1)
{
if(a+b < 50)
cout sorry
else
{
cout wo
}
}
elseif(math ==2)
if(a-b < 100)
cout sorry
}
else
{
cout wo
}
}
else
{
cout no matching math found
}

sure there are better solutions out there, but for the beginning its the simplest I got in mind this quick.

btw instead of using if Statements you could also use a switch

Answer 2

don't know if I get you right but
if((a+b < 100) || (a-b <100))
{
cout << "Sum is less" << endl;
}
else
{
cout << "match 100" << endl;
}

Answer 3

I mean this way

Answer 4

#include <iostream>
using namespace std;

int main()
{
int a = 30;
int b = 12;
int sum = a + b;

if (sum>50){cout<<"wow"<<endl;
}else {cout<<"sorry"<<endl;
}

return 0;
}
