Solution for Exercise 20-4

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char *input;

    /* allocate memory */
    input = (char *)malloc(sizeof(char)*1024);
    if(input==NULL)
    {
        puts("Unable to allocate buffer! Oh no!");
        exit(1);
    }

    /* use the memory */
    puts("Type something long and boring:");
    fgets(input,1024,stdin);
    puts("You wrote:");
    printf("\"%s\"\n",input);

    return(0);
}

Output

Type something long and boring:
It was a dark and stormy night. Suddenly! The program crashed!
You wrote:
"It was a dark and stormy night. Suddenly! The program crashed!
"

Notes

* The fgets() function retains the newline typed to end input, which is why the final double-quote character output from the program appears on a line by itself.
