(Count occurrence of each letter in a string) Write a function that counts the occurrence of each letter in the string using the following header:

void count (const char s[], int counts [])

where counts is an array of 26 integers. counts [0], counts [1], ..., and counts [25 ] count the occurrence of a, b, ..., and z, respectively. Letters are not case-sensitive, i.e., letter A and a are counted the same as a. Write a test program that reads a string, invokes the count function, and displays the non-zero counts as shown in the following sample run: (Note that c: 1 time are separated by exactly one space.) Show the Sample Output Using the Preceding Input Execution Result:
