Description
Exercise 1
The factorial of a nonnegative integer n is written n! and is defined as follows: n! = n * (n – 1) * (n – 2) * ……1 and
n! = 1 (for n = 0)
For example, 5! = 5 * 4 * 3 * 2 * 1, which is 120
Write a C program that reads a nonnegative integer and computes and print its factorial using a while loop.
Exercise 2
A company pays its employees a salary between $200 to $1500. Write a C program (using arrays of counters) that determine how many of the employees earned salaries in each of the following ranges ( assume that each employee’s salary is truncated to an integer amount). The program should stop entering the salaries, when the user input -1 a salary.
- $200 – $299
- $300 – $399
- $400 – $499
- $500 – $599
- $600 – $699
- $700 – $799
- $800 – $899
- $900 – $999
- 1000 and above
Exercise 3
Write a C program to multiply the content of array A and B and store it in a new array called C.
int A[5] = { 10, 20, 30, 40, 50};
int B[5] = { 34, 67, 12, 89, 12};
Exercise 4
Write a C program that will enter a name, store it in an array and then display it backwards. Allow the length of the line to be unspecified (terminated by pressing the Enter key). , but assume that it will not exceed 20 characters.
Exercise 5
Implement a function called convertToUpperCase ( ) which take a string (a mix of uppercase and lower case letters) as an argument and display the string in only upper case letters.
void convertToUpperCase (char a[ ], int size );
In your main function declare a character array called address and copy the address “SLIIT, New Kandy Road, Malabe” using string copy function. Pass the address to the convertToUpperCase ( ) function and display the address in capital letters.
Hint : ‘a’ – 97, ‘z’ – 122, ‘A’ – 65, ‘Z’ – 9
