CODE EXAMPLE FOR CPP

memeset() in c++

// CPP Program to demonstrate that we can use memset() to
// set all values as 0 or -1 for integral data types also
#include <bits/stdc++.h>
using namespace std;
  
// Driver Code
int main()
{
    int a[5];
  
    // all elements of A are zero
    memset(a, 0, sizeof(a));
    for (int i = 0; i < 5; i++)
        cout << a[i] << " ";
    cout << endl;
  
    // all elements of A are -1
    memset(a, -1, sizeof(a));
    for (int i = 0; i < 5; i++)
        cout << a[i] << " ";
    cout << endl;
  
    // Would not work
    memset(a, 5, sizeof(a)); // WRONG
    for (int i = 0; i < 5; i++)
        cout << a[i] << " ";
}
