Synopsis
#include

double sqrt(double x);

float sqrtf(float x);
Returns
The value of the square root.
Example
double x=25.0;

double y;

y=sqrt(x);
srand
Uses the argument as a seed for a new sequence of pseudorandom numbers to be returned
by subsequent calls to
rand . If srand is then called with the same seed value, the
sequence of pseudorandom numbers is repeated. If rand is called before any calls to
srand have been made, the same sequence is generated as when srand is first called with
a seed value of 1.
Synopsis
#include

void srand(unsigned int seed);
Example
int i;

srand(1001);

i=rand();
sscanf
Reads formatted data from a string.
Synopsis
#include

int sscanf(const char *s, const char *format, ...);
