Question

Intro to prog c question!!1

Write in the text box window below a function countInFile that takes as parameters a file name fname (of type char[]) and a character c and that returns the number of times character c occurs in the file. You need to open the file, then read characters (one by one) in a loop and count, and, finally, close it before returning the count.

The function prototype is:

int countInFile(char fname[], char c);

For example if a file named “text” has the content “all men are created equal”, then calling

countInFile(“text”, ‘e’)

should return 5.

Ensure the code is correct, aligned, and indented properly. Use meaningful variable names.
