/*

Here is a code snipped with some comments,

I haven't tried compiling it, but I guess you get the general idea

*/

#include <stdio.h>

int convert(char key)

{

        char charIndex[5]=('A','B','C','D','E');

        int intIndex[5]=(1,2,3,4,5);

        for(int i=0;i<sizeof(charIndex);i++)

                {

                        if(key==charIndex[i])

                        {

                                return intIndex[i];

                                /* Return the integer in the same position as the Character in your conversion array */

                        }

                }

        return 0;

//if no match, return zer0

}

main()

{

char myChars[5]=('A','B','C','D','E'); /* Assume these are the chars from your file in an array */

int myIntegers[5];

for(int i=0;i<sizeof(myChars);i++)

        {

                myIntegers[i]=convert(myChars[i]);

        }

return 0;

}
