Question

Translate the following C program into NASM.

 

#include <stdio.h>

int main()

{

    int x = 0;

    char sent[20];

    printf("Enter sentence: ");

    scanf("%[^\n]s", sent);

 

    while (sent [x] != '\0') {

        if (sent[x] >= 'a' && sent[x] <= 'z') {

            sent[x] = sent[x] & 0xDF;

        }

        x++;

    }

    printf("%s \n", sent);

}

 

Use indexing (the [ebx] form). You can use the following pseudocode in the “bss” to allocate the array:

 

    slen equ 20

    sent resb slen

 

Note: the scanf format string of “%[^\n]s” keeps reading characters until the newline (otherwise it would end at the first space).
