#include <math.h>

//get square root of a number "b"
int main(){
  	int a = 2; //declare number you want to take square root of
  	int sqrtNum = sqrt (a); //assign the sqrt value to a variable
  	cout << sqrtNum << endl;
	return 0;
}

Example 2: square root c++

#include <stdlib.h>
#include <stdio.h>
#include <math.h>

/*

*/

int main(){
float num, raiz;
printf("enter a number: \t");
scanf("%f",&num);
raiz = sqrt(num);
