Short Simple Exercise Please Explain Me

[WalterCC]

Hello. I dont understand this program. Even if I make changes in him , I still dont understand . Can u please explain it to me ...please.

#include<iostream>
using namespace std;
int main(){
int i,t=4;
for(i=3;i<=7;i++) t=t+i;
cout<<t;
}

The output result is 22 , and i DONT understand why .

Since the output is 29, I guess that would be confusing.

Perhaps you mis-read the <=7 as <7.

Anyway, to resolve confusion, add some debug printing.

#include<iostream>
using namespace std;
int main(){
int i,t=4;
for(i=3;i<=7;i++) {
    cout << "Adding " << i << " to " << t << endl;
    t=t+i;
    cout << "T is now " << t << endl;
}
cout<<t;
}
