Answer 1

Answer:

#include <stdio.h>

int main() {

 char s1[100] = "programming ", s2[] = "is awesome";

 int length, j;

 // store length of s1 in the length variable

 length = 0;

 while (s1[length] != '\0') {

   ++length;

 }

 // concatenate s2 to s1

 for (j = 0; s2[j] != '\0'; ++j, ++length) {

   s1[length] = s2[j];

 }

 // terminating the s1 string

 s1[length] = '\0';

 printf("After concatenation: ");

 puts(s1);

 return 0;

}
