    help with getchar() and arrays

    can someone please tell me why this piece of code does not work properly?...im trying to get input using getchar and put it into an array. then, print the contents of the array.

    Code:
    #include <stdio.h>
    #include <ctype.h>
    #define ARRAY_SIZE 1000
    
    int main(int argc, char **argv) {
    
        int input;
        char Description[ARRAY_SIZE];
        int counter = 0;
        while((input = getchar()) != EOF) {
    
            Description[counter] = input;
            counter++;
            input = getchar();
        }
    
        printf("%s",Description);
    
        return 0;
    
    }

    You are using getchar twice!

    Get rid of this line, otherwise you'll only read every other character:
    Code:
    input = getchar();
    And you might want to change this:
    Code:
    while((input = getchar()) != EOF) {
    to
    Code:
    while((input = getchar()) != EOF && input != '\n') {
    to only read one line.
