Hello everybody, ive only been learning C for about a month so please forgive me if my code is messy or unclear! I have written a simple program which creates a text file, reads from it and then writes the output backwards to another file; it seems to work apart from in the output file i get a load of gibberish after the original reversed text. the code is listed bellow.
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
char file_name[100]; /*declare char arrays to hold file name and text*/
char file_text[500];
char c; /*char to hold text characters */
int counter1, counter2;
FILE *input_file, *input1_file, *output_file; /*declaration of file pointers */
printf("\nenter the name & extension of text file to create:");
scanf("%s", &file_name);
printf("\nenter the text to be reversed:");
scanf("%s", &file_text);
input_file = fopen(file_name, "w");
if(input_file == NULL){ /*if it is a null pointer return error to operating system*/
printf("Error: could not create file");
exit(1);
}
else{
for(counter1 = 0;file_text[counter1];counter1++){ /*eneter each character from the array into the file*/
fputc(file_text[counter1], input_file);
}
}
printf("\nFile sucessfully read.\n");
fclose(input_file);
input1_file = fopen(file_name, "r");
if(input1_file == NULL){
printf("Error file could not be read");
exit(1);
}
else{
while(1){
c = fgetc(input1_file);
if( c == EOF){ /*if it reaches the end of the file, break the loop */
break;
}
else if (counter2 < 200){
c = file_text[counter2]; /*assign the character to elements of the array */
counter2++;
}
}
}
fclose(input1_file);
output_file = fopen("output.txt", "w");
if(output_file == NULL){
printf("Could not write file");
exit(1);
}
else{
counter1--; /*it incremented one too many */
for(;file_text[counter1];counter1--){
if(counter1 != 0){
fputc(file_text[counter1], output_file); /*output each character to the file individually starting with the last element in the array*/
}
}
}
printf("\n\nprocess completed");
fclose(output_file);
return 0;
}Any help in resolving my little problem would be much appreciated, thanks in advance.
