Translate the following C program to Pep/9 assembly language.

#include <stdio.h.>

int main() {

int numitms,j,data,sum;

scanf("%d", &numitms);

sum=0;

for (j=1;j<=numitms;j++) {

scanf("%d", &data);

sum+=data;

}

printf("sum: %d\n",sum);

return0;

}

Please test the answer using Pep/9. Thank you so much!

Answer #1

The Pep/9 translation the C code in the assembly language is given as follows:

main: SUBSP 2,i
DECI numItms,i
DECI j,j
DECI data,d
DECI sum,s
LDWA numItms,i
sum: .EQUATE 0
LDWA 1,i
STWA j,j
for: CPWA numItms, j
BRGE endFor
STRO msg,d
DECO j,s
LDBA '\n',i
STBA charOut,d
LDWA j,s ;j++)
ADDA 1,i
STWA j,s
BR for
endFor: ADDSP 2,i ; STOP
msg: .ASCII "Sum = \x00"
.END

------------------------------------------------

The above given code is the translation of the C code into the Pep 9 assembly language.
