C PROGRAMMING -Algorithm

Step-1: Start
Step-2: Read the number n
Step-3: Check for the number if less than zero. If it is true than goto step-4 other wise goto step-5
Step-4: Display the error than goto step-7
Step-5: In the while loop check (sqrt!=temp) if true execute, otherwise goto step-6
- Temp = sqrt
- Sqrt = (n/temp+temp) / 2
Step-6: Display the square root of n
Step-7: Stop
