// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
double num;
// read discriminant
cin>>num;
// calculate square of the input
double result=num*num;
// print the square number
cout<<result<<endl;
return 0;
}
Explanation:

See Explaination
Explanation:
#include <iostream>
#include <string.h>
using namespace std;
char *mixem(char *s1, char *s2);
int main() {
cout << mixem("abc", "123") << endl;
cout << mixem("def", "456") << endl;
return 0;
}
char *mixem(char *s1, char *s2) {
char *result = new char[1 + strlen(s1) + strlen(s2)];
char *p1 = s1;
char *p2 = s2;
char *p = result;
while (*p1 || *p2) {
if (*p1) {
*p = *p1;
p1++;
p++;
}
if (*p2) {
*p = *p2;
p2++;
p++;
}
}
*p = '\0';
return result;
}
