My C program - Help me in identifying anything wrong with it

[xiao_xiao]

---

bacn wala nako natarong ug copy kang smarkies. i-try lng na kang smarkies peru ibaylo lng ang order sa input

[marcdaven]

Copied the original code by smarkies and edited..

The same result ra giahpon bro. T_T I think I'll have to go with the magic line nga

void main(void);
{
 .
 ..
 ...
 printf("Choices: ... ");
 c=getche();
}

Anyways, naka decide diay ko nga ang corrected program ni smarkies (original one) ang akong gamiton kay simple ra (Bahala na nagbaylo ang order sa paginput.. ). If I will use man gud the other programs introduced to me, musaka nya ang kilay sa among maestra ngano advanced kaayo akong program. xD

Nonetheless, I would like to express my eternal gratitude to all programmers who patiently helped me in my endeavor. MABUHAY KAYONG LAHAT!

I managed to compile a c program under visual studio 2008. pwede ra mn diay isulod sa c++ file/project.

i think mao na ni. i found out nga case sensitive ang compiler so instead of if(c=='A'), use if(c=='a')... I'm not sure though but mao akong na-obserbahan sa akong compiler. hehe

#include<stdio.h>
#include<conio.h>
int add(int, int);
int subtract(int, int);
float divide(int, int);
int multiply(int, int);

int main()
{
 int a, b, d, e, f;
 float g;
 char c;
 
 printf("\nEnter two integers separated by a space: ");
 scanf("%d %d", &a, &b);

 printf("Select an operation:\n(a) Add\n(s) Subtract\n(d) Divide\n(m) Multiply\n");
 printf("Choice: ");
 scanf("%c",&c);

 c = getche();

 if (c=='a')
 {
  d=add(a, b);
  printf("\nThe sum of %d and %d is %d\n", a, b, d);
  
 }

 if (c=='s')
 {
  e=subtract(a, b);
  printf("\nThe difference of %d and %d is %d\n", a, b, e);  
 }

 if (c=='d')
 {
  g=divide(a, b);
  printf("\nThe quotient of %d and %d is %.2f\n", a, b, g);  
 }

 if (c=='m')
 {
  f=multiply(a, b);
  printf("\nThe product of %d and %d is %d\n", a, b, f);  
 }
 getch();
 return 0;
}


int add(int a, int b)
{
 return (a+b);
}
int subtract(int a, int b)
{
 return (a-b);
}
int multiply(int a, int b)
{
 return (a*b);
}
float divide(int a, int b)
{
 return ((float)a/b);
}

if you want to be sure kung case sensitive ba ang input.
use

if (c=='a' || c=='A')
{
   d=add(a, b); 
   printf("\nThe sum of %d and %d is %d\n", a, b, d);
}

Bro, ganahan man gud ang among maestra nga void main(void) among gamiton..
Then, I don't know if pwede ba mugamit ug getche(); kay wala pa man na gitudlo sa amo bro..

[marcdaven]

if you want to be sure kung case sensitive ba ang input.
use

if (c=='a' || c=='A')
{
   d=add(a, b); 
   printf("\nThe sum of %d and %d is %d\n", a, b, d);
} 

Hala, bitaw sa.. Pwede pa man diay ma modify ang input, pwede ra capatial A ba or di.. Thanks ani nga idea!

[xiao_xiao]

aw pwede ra mn void main(void).
int main() mn gud to ako sauna.
kung mag void ka, ayaw na pag return 0;
pwede ra mn cguro getche(); hehe

[xiao_xiao]

pwede ra mn cguro na ilisan nimo ug getch() instead of getche()... specifically c = getch();
ok ra mn sa akong compiler. awat2x ra mn ko anang getche() sa mga uban ga post diri. hehe.

[marcdaven]

Haha! Di ko ganahan mugamit ug program nga wla ko naka sabot sa each part sa program. xD

[xiao_xiao]

revised...
getch() na akong gamit, dili na getche... tapos case insensitive na.

#include<stdio.h>
#include<conio.h>
int add(int, int);
int subtract(int, int);
float divide(int, int);
int multiply(int, int);

int main()
{
 int a, b, d, e, f;
 float g;
 char c;
 
 printf("Enter two integers separated by a space: ");
 scanf("%d %d", &a, &b);

 printf("Select an operation:\n(a) Add\n(s) Subtract\n(d) Divide\n(m) Multiply\n");
 printf("Choice: ");
 scanf("%c",&c);

 c = getch();

 if (c=='a' || c=='A')
 {
  d=add(a, b);
  printf("\nThe sum of %d and %d is %d\n", a, b, d);  
 }

 if (c=='s' || c=='S')
 {
  e=subtract(a, b);
  printf("\nThe difference of %d and %d is %d\n", a, b, e);  
 }

 if (c=='d' || c=='D')
 {
  g=divide(a, b);
  printf("\nThe quotient of %d and %d is %.2f\n", a, b, g);  
 }

 if (c=='m' || c=='M')
 {
  f=multiply(a, b);
  printf("\nThe product of %d and %d is %d\n", a, b, f);  
 }

 getch();
 return 0;
}


int add(int a, int b)
{
 return (a+b);
}
int subtract(int a, int b)
{
 return (a-b);
}
int multiply(int a, int b)
{
 return (a*b);
}
float divide(int a, int b)
{
 return ((float)a/b);
