2. WAP to calculate simple interest by passing the principal amount, rate of interest and time period as argument to function. Make rate of interest and time period default argument with default values 1.2 and 3 respectively
3. Raising a number n to power p is the same as multiplying by itself t times. Write a function called power ( ) that makes a double value for n and an int value for p and returns the result as double value. Use default argument of 2 for p, so that if this argument is omitted, the number will be squared. Write a main( ) function that gets values
from the user to test this function.
4 Write a function “increment” which takes two arguments and increment the first argument by second pass the argument to this function from main and print the increment value in the main function (use reference variable).
