Find Square Root of Any Number in C

Find Square Root of Any Number Program in C

For calculate square root of any number we multiply number by 0.5 because square root of any number means power of 1/2 and 1/2=0.5.

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

void main() 
{ 
int num,ans; 
clrscr(); 
printf("Enter any number: "); 
scanf("%d",&num); 
ans=pow(num,0.5);
printf("\n Square root of %d is: %d",num,ans); 
getch(); 
} 

Enter any number: 9
Square root of 9 is: 3

Explanation of Program

• For calculate square root of number we multiply number by 0.5 because square root of any number means power of 1/2 and 1/2=0.5.
• pow() is a predefined function in math.h header file, it is used for calculate power of any number.

Square Root of number by passing values in function

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

int square(int); 
void main()
{
int num;
clrscr();
printf("Enter any number: ");
scanf("%d",&num);
printf("\n Square root of %d is: %d",num,square(num));
getch(); 
}
int square(int num)
{
int ans;
ans=pow(num,0.5);
return(ans); 
getch();
}

Enter any number: 64
Square root of 3 is: 4
