    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.
