Print an array in blocks of five?

[antonio.gor]

I wrote this code for a Caesar cipher but am stuck at the end.

I have three function:
processFile() opens a file (congress.txt) and stores it in an array.
cipher() shifts all the letters up one letter.
outputCode() is supposed to print the new text in blocks of five, ten blocks per line.

That is where I am stuck. I am able to go to a new line every 50 characters but can't figure out how to get the characters in blocks of five.

My ouput:

Desired output:

Any suggestions?


Here is my code:

#include <stdio.h>
#include <stdlib.h>


FILE *csis;


//Functions to be used.
void processFile(int *store);
void cipher(int *store, int *code);
void outputCode(int *code);


int main()
{
    csis = fopen("csis.txt", "w");


    int store[300], code[300], i;


    //Order of functions to be called.
    processFile(store);
    cipher(store, code);
    outputCode(code);


    fclose(csis);
    return 0;
}


//Function to open the Congress text
//file and set it up for cipher.
void processFile(int *store){


    int i;
    char a = 0;
    FILE *f = fopen("congress.txt", "r");


    //Stores lowercase letters as uppercase, etc.
    for (i = 0; !feof(f) && i<299;){
        fscanf(f, "%c", &a);
        if (a <= 'Z' && a >= 'A'){
            store[i] = a;
            i++;
        }
        if (a <= 'z' && a >= 'a'){
            store[i] = a - 32;
            i++;
        }
    }
    store[i]='\0';
}


//Function to execute the shift by 1 letter.
void cipher(int *store, int *code){


    int i;


    for (i = 0; store[i] != 0; ++i){
        if (store[i] <= 'X' && store[i] >= 'A'){    //Tests to see if the letter is between A and X.
            code[i] = (char)(store[i] + 1);         //Shifts letter by one characters.
        }
        if (store[i] >= 'Y' && store[i] <= 'Z'){
            code[i] = (char)(store[i] - 25);        //Shifts Y and Z.
        }
    }


    for(; i<300; i++) code[i]=0; //Pad with zeros.
}


//Function to output the final encoded message in blocks.
void outputCode(int *code){


    int i, a, b;


    for (a = 0; code[a] != 0; ++a){


        //New line every 50 characters.
        if (!(a % 50)){
            printf("\n");
            fprintf(csis, "\n");
        }


        printf("%c", code[a]);
        fprintf(csis, "%c", code[a]);


    }
}

Well you figured out this much.

How hard can it be to have a %5 to print spaces as well?

Also, make your csis variable local to main, and pass it as a parameter when needed.

But since you've just copied code from somewhere else, I guess you'll never figure it out.
