Question

True or False: It's easy to loop through an array using a for loop in C++ because you can use the .size() function to get the total number of spaces in the array

True or False: It's easy to loop through a vector using a for loop in C++ because you can use the .size() function to get the total number of spaces in the vector

Answer 1

1.False it is not very easy to loop through an array using a for loop in c++ beacuse we cannot use the .size() function as it is not available in the c++.

code to demonstrate the above statement

#include<bits/stdc++.h>
using namespace std;
int main(){
    int a[]={1,2,3,4,5,6};
    for(int i=0;i<a.size();i++){
        cout<<a[i]<<" ";
    }
}

the above code will show an error which is shown below

2.True in vector It easy to loop through a vector using a for loop in C++ because you can use the .size() function to get the total number of spaces in the vector

program to demonstrate the above statement

#include<bits/stdc++.h>
using namespace std;
int main(){
    vector<int>v{1,2,3,4,5,6};
    for(int i=0;i<v.size();i++){
        cout<<v[i]<<" ";
    }
}

tje output of the following program will be
