Answer to Question #272283 in C# for chi

Question

write a program that calculates the power value of the input base number and exponent number. Apply three solutions using the three looping statements: Sample input/output dialogue Enter base no. 5 Input data Enter exponent no. 3 Second input data Power value: 125 Output value (The computation is: 53 = 5 * 5 * 5 = 125)

1st Solution – using for loop

2nd Solution –using while loop

3rd Solution-­‐ using do while loop
