whats wrong in this program?It multiplies and gives wrong answer when i run this.?

Question

#include
#include
void main();
{
int a,b,c;
clrscr();
printf("enter the values for a and b\n");
scanf("%d%d",&a,&b);
c=a*b;
printf("product is %d",c)
getch()
}

Answer 1

c=a*b;
printf("product is %d",c);
getch();

Answer 2

Don't know what the getch() is trying to accomplish, otherwise it should work. When trying to figure out what is going on, either: put in copious quantities of print statements (eg after ever line); or, BEST OF ALL, use a debugger. Start the program up in your debugger, and go through it STEP BY STEP (line by line), checking the values of the variables after each step. That (in the debugger) is where a programmer spends over 50% of their time, so, make yourself at home there.

#include

int main() {
int a,b,c;
printf("enter the values for a and b\n");
scanf("%d%d",&a,&b);
c=a*b;
printf("product is %d",c);
}

$ ./a.exe
enter the values for a and b

product is 30

Answer 3

/*Make sure you give a seperator for getting the values of a and b */
scanf("%d %d", &a, &b);
c=a*b;
/* ; is missing */
printf("product is %d", c);
/* ; is missing */
getch();

Answer 4

your scanf function is wrong,

check if a and b is getting the proper values.

put the line .......printf("%d %d, a,b )

to check the values for a & b.

happy programming..........

Answer 5

how did u give input??
it should be given as
space
u should not press enter between the values of a and b...
Try this....

Answer 6

u did not end getch() with ";". type getch();
