Using functions, string manipulation and dynamic memory allocation
A common typing e
or is to place your hands on the keyboard one position to the right of the co
ect position. The “Q” is typed as “W” and “J” is typed as “K” and so on. Your task is to write a C program to decode a message type in the manner.
The input consists of a string which contains uppercase letters, spaces, periods and slashes (/). Spaces remain as spaces in the output. Otherwise, you are to replace each letter, period and slash with the symbol immediately to its left on the keyboard.
Sample input: YJOD OD JSTF
Sample output: THIS IS HARD.
Your program should do the following:
· Prompt for and read an input string.
· Use strlen to find the length of the input string.
· Dynamically allocate memory to hold the output string, which is to be the same length as the input string. Don’t forget \0.
· Write a function which takes a single character from the input string and returns the co
ect character of the output string.
· Build the output string one character at a time, using the above function.
· Display the output string.
