Output

Enter any Number: 9
Squre of 9 is: 3

Explanation of Program

• For calculate sqare 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 forcalculate power of any number.
