Question

Consider the following code that repeats a C++ string three times.

string a = "Hello";

string b = a + a + a;

Suppose s is a C string, and t is declared as

char t[100];

Write the equivalent code for C strings that stores the threefold repetition of s (or as much of it as will fit) into t.

(C++)

Answer 1

#include <stdio.h>
#include <string.h>

int main() {
    char s[] = "Hello";
    char t[100];
    strcpy(t, s);
    strcat(t, s);
    strcat(t, s);
    printf("%s\n", t);
    return 0;
}
