pow(x,y) is not working

krishnampkkm

Hiii

I tried to write a small program in C.

[code]#include
#include
int main()
{
printf("

the 4^3 = %d",pow(4,3));
return 0;
}[/code]

And I compile like[b] $gcc -lmath pgm1.c [/b]

but it doesn't work..What may be the reason.

Thanking you

It compiles just fine without '-lmath'.
pow is expecting a return value of double, so you may want to change '%d' to something like '%.0f'. (testing it with %d showed 4^3=0)

try this code I tried it using code blocks I use Ubuntu linux gcc4.4

include
#include

int main()
{
int a,b,c;

a=4;b=3;
c=pow(4,3);

printf("

the 4^3 = %d",c);

return 0;

}

its working fine in gcc , just check by compiling with gcc name.c and ./a.out
no need to use -lpm
