Hey ppl,
I have a problem related to a C program.
I have a problem related to a C program.
#includeNow, surprisingly the output is 7. I am not returning anything from the function. It should return garbage value. But how am i getting the correct output????#include int sum(int a,int b) { int c=a+b; } int main() { int a=5,b=2; printf("%d",sum(a,b)); getch(); return 0; }

ReyaIf i run the program using online compiler it returns the output as 0.Whereas in devcpp it returns 7. -
Pensu@praveena: exactly my point....how it can print 7 while i am not returning anything.

Bharath51i think....it defaultly return last operation performed by the compiler......
i tried this....
as
a+b;
a-b;
a*b;
a/b;
the last statement "a/b" returned to the function......so the c compiler default return some thing......that is last operation performed..... -
gaurav.bhorkarThis may also be because of compiler optimization. Did you get a warning?
PS: I didn't compile your code -
ayusha patnaiki think its by default since u r using it for a single tym...if u use multiple operations thn the correct output would be avilable fr a single operation...means it is set as a default .
