C++ program to reverse a string that a user will input, for example, if the user enters "hello," then "olleh" will be printed as output.
C++ program
#include <iostream>
#include <cstring>
#include <cstring>
using namespace std;
int main()
{
char a[100], b[100];
int i, j, l;
cout << "Enter a string to reverse\n";
cin.getline(a,100); // cin >> a; can be used for a string without a space
l = strlen(a);
for (i = l-1, j = 0; i >= 0; i--, j++)
b[j] = a[i];
b[j] = '\0';
cout << "Reverse of the string: " << b << "\n";
return 0;
