How do you set i<= array length

[vichu99]

Hello, how do you stop the iteration when it has reached the array length?


#include <iostream>
#include <cmath>
using namespace std;

int main(){

int b[]={1,2,3,4,5,6,7};

for(int i=0; i<=array.length; i++){ //instead of array.length?
cout <<b[i]<<", ";

int c;
cin>>c;

}

Universal way for constant arrays. Works for c also:
#define arrlength(x) sizeof(x)/sizeof(x[0])
because sizeof is rather also precompiled macros result will be as fast as possible because on compilation stage you will get exactly constant

Thanks, what do you write in the code?

    int array[]={1,2,3,4,5,6,7};
    const int length = sizeof(array) / sizeof(array[0]);

or possibly use std::vector instead.
