The program has to be written in C programming Language

Question: We have a bunch of items categorized by the letters of english alphabet. We receive different amounts of them over time and we want to keep track of how much of each lettered item we have received. Maintain a running total of the number of a, b, c, ..., x, y, z items we have received.

Example output

The program will read from the terminal using scanf or fgets a single character descriptor---a key---followed by a count of the number of oberservations of that key. Then at the end of the program when the user quits or indicates they want to quit (by typing X) or mistypes something, the total of sum of each lettered item is printed if their sum is greater than 0.

The summary will be like

a - 1 b - 1 

if the user typed following input: a 1 b 1. Only positive counts will be displayed.
