Practical C Programming

How to do it…

1. Create a string called str. The last element in the string will be a null character, \0. 
2. Define another string called chr of matching length, to store the characters of str:

char str[80],chr[80];

3. Prompt the user to enter a string. The entered string will be assigned to the str string:

printf("Enter a string: ");scanf("%s",str);

4. Compute the length of the string array, str, using strlen:

n=strlen(str);

5. Define an integer array called count to display the number of times the characters have occurred in str:

int count[80];

6. Execute chr[0]=str[0] to assign the first character of str to chr at index location chr[0].
7. The count of the character that's assigned in the chr[0] location is represented by assigning 1 at the count[0] ...
