Thread: Storing the result of execvp to a char array in C

I would like to know how to store the result of execvp to a char array as a string.

Below is my code:

Code:

int main () {
    char response[1000];
    char *buffer[100];
     int pid, status;
     printf("Please enter the shell command:  ");
     scanf("%s",&response);
     pid = fork();
     if (pid < 0) {
                    printf("Unable to create child process, exiting.\n");
                    exit(0);
                    }
     if (pid == 0) {
                printf("I'm the child.\n");
                *buffer = response;
                execvp(*buffer,buffer);
                printf("execvp failed\n");
                     } 
                     
     else{
          wait(&status);
          exit(0); 
          }
}

If a user types "ls" execvp displays the result of "ls" to the screen. I would like to store this in a char array as a string. Can anyone help me?
THanks in advance.
