I had just started learning C and just joined the group.
Presently I am reading the book "sams teach yourself C in 24hrs 2nd ed"
The below source code is from page 151 of the book, I compiled it (using plato)
but it gave me an error.
I noticed that the sqrt function referred to nothing.
But in the book it compiled successfully and the printed output was correct.
so my question is; was the author mistaken & are there such similar errors in
the book (for those who have read it before)?
Or is my compiler the problem.
Also is it possible to run C codes on Microsoft visual Studio C++
#include<stdio.h>
#include<math.h>
main()
{
double x,y,z;
x=64.0;
y=3.0;
z=0.5;
printf("pow(64.0,3.0) returns: %7.0f\n",pow(x,y));
printf("sqrt(64.0) returns: %2.0f\n",sqrt);
printf("pow(64.0,0.5) returns: %2.0f\n",pow(x,z));
return 0;
}
N.B
There is something similar in pg 150 of the same book
printf("The cosine of 45 is : %f.\n",cos);
