[C] Syntax Tips

// Prints help message to the console
// Returns a string
char * helloWorld(char * name) {
    char * answer = malloc(strlen(name) + 8);
    printf("This prints to the console when you Run Tests");
    strcpy(answer, "Hello, ");
    strcat(answer, name);
    return answer;
}

Solution

char *encloseInBrackets(char *inputString)
{
	int N=strlen(inputString);

	for(int i=N;i>0;i--)
		inputString[i]=inputString[i-1];
	inputString[0]='(';
	inputString[N+1]=')';
	inputString[N+2]='\0';

	return inputString;
