Setting int pointers to one function (not using five functions!)
I am trying to make the follwing five functions into one function. It counts each vowel and lists the frquency of each vowel.
The printf statements are fine it is merely the function that I am having problems with. I know that I need to set int pointers to each vowel but I am not entirely sure how to do this.
Here is my program, please not that I am only interested in the bottom part which lists the frquency's of each vowel (named functions vowelfrequencya e i o u.
Code:
#include<stdio.h>
#include<string.h>
/*Declaring the functions of the program*/
int printablecount(char[]); /*The printable characters count funtion*/
int CountNonPrint (char[]); /*The non-printable characters count function*/
int consonant_frequency( char[]); /*The consonant count function*/
int vowel_frequency(char[]); /*The vowel count function*/
int vowelfrequencya(char[]);
int vowelfrequencye(char[]);
int vowelfrequencyi(char[]);
int vowelfrequencyo(char[]);
int vowelfrequencyu(char[]);
int main(void) /*Declaring Main*/
{
/*Opens the text file from a remote source*/
FILE *fp;
/*Setting the variables*/
char ch;
char sentence[81];
int count = 0;
int cf, vf, pc, np, vfa, vfe, vfi, vfo, vfu;
/*Opens the text file from a remote source*/
fp = fopen("1.txt","r");
/*Sets a null if the file cannot be read from the remote source*/
if( fp == NULL )
printf("File could not be opened\r\n");
else

I know large parts of the program are completed the complicated way (e.g. the consonant count) but I am fairly happy with it.
Cheers for your help
