Synopsis

#include <math.h>

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 <stdlib.h> 

void srand(unsigned int seed);

Example

int i;

srand(1001);

i=rand();

sscanf

Reads formatted data from a string.

Synopsis

#include <stdio.h>

int sscanf(const char *s, const char *format, ...);
