Assignment 8, C (gcc)

Assignment 8

//gcc 5.4.0
/*

Problem 1:
Write a C program that searches for a given value in an array of characters. The program should return the index of the value if it exists, otherwise, it should print -1. You can initialize the array in your code by an input string.      
(a)	Write a pseudocode for this program
(b)	Implement your pseudocode in C.
(c)	Test You program using the following code:
a.	Input string: “The George Washington University” and search for the characters: ‘W’, ‘w’, ‘!’, ‘n’, ‘ ‘

Problem 2:
Write a C program that replaces each occurrence of a given value in an array by a new value.   
(a)	Write a pseudocode for this program
(b)	Implement your pseudocode in C. (due next lab)
(c)	Test You program using the following:
a.	The character does not exist in the array. 
b.	Input sting: “aaaaaaaaaaaaaaaaaaaaa” and the given character is ‘a’.
