Convert C code to assembly

Question

I need to translate this code to assembly language code

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

int main(void)
{
    int answer, i;
    int right, wrong;
    right = 0;
    wrong = 0;

    for(i =1; i < 11; i = i+1){
        printf("What is %d + %d? ", i,i);
        scanf( "%d", &answer);

        if(answer == i + 1) {
            printf("right!  ");
            right++;
        }
        else {
            printf("Sorry, you're wrong.    ");
            printf("The answer is %d.   ", i + 1);
            wrong++;
        }
    }
    printf("You got %d right and %d wrong. ", right, wrong );
    return 0;
}

I just need to know how to combine the variable with a string in assembly language, as in the above C code. I think I can handle everything else. Can anyone tell me. Should I use some kind of link [].

Note. I use MASM and the development of the Kip Irvine build language for x86 processors. Book of the 6th edition.

update the code that I tried to write to MASM from one of the responder's answers, I get an error all the time. As I said, I use the assembly language Kip Irvine, so I need to include the INCLUDE Irvine32.inc library link

  

this is an error → → programb.obj: error LNK2019: unresolved external symbol _scanf referenced by the function _main @ 0

  

TURN ON Irvine32.inc

-

.data
string1 db "What is %d + %d?  ", 0
string2 db "%d", 0
string3 db "right!  ", 0
string4 db "Sorry, you're wrong.   The answer is %d", 10, 0
string5 db "You got %d right and %d wrong.", 10, 0


answer dd 0
right  dd 0
wrong  dd 0

PS Re: previous answers, it is usually not useful to look at the assembly code generated by the compiler if you are trying to learn the assembly. Even without optimization enabled, the output is not intended for people to read.

Answer 4

As an example, this line in the C programming language:

printf("\n%d%s%d\n\n",num1," is not equal to ",num2);

is equivalent to:

printf PROTO arg1:Ptr Byte, printlist:VARARG
.data
msg1fmt byte 0Ah,"%d%s%d",0Ah,0Ah,0
msg1 byte " is not equal to ",0
num1 sdword 5
num2 sdword 7
.code
main proc
INVOKE printf, ADDR msg1fmt, num1, ADDR msg1, num2
ret
