Sample Input:
Please enter 1 for Simple Calculator
Please enter 2 for Scientific Calculator
2
Please enter 1 for cos:
Please enter 2 for sin:
Please enter 3 for tan:
Please enter 4 for cosec:
Please enter 5 for sec:
Please enter 6 for cot:
Please enter 7 for log:
Please enter 8 for square:
Please enter 9 for round:
8
Please enter the value 36
Sample Output
The square root of number is: 6
