How to write a c program to read a char & print next char ( file to file ) in C Programming Language ?
Solution:
/* Read a char & print next char ( file to file ) : A character should be written in the file named "readfile.txt" beforehand and we will take this as input to be manipulated and finally written into the file named "writefile.txt" */
#include <stdio.h>
int main()
{
FILE *fp,*fp1;
int ch;
fp=fopen("readfile.txt","r");
fp1=fopen("writefile.txt","w+");
if(fp == NULL)
{
printf("\nThe file was not found\n");
}
while((ch = fgetc(fp)) != EOF)
{
if(ch>96 && ch<122)
{
ch++;
fprintf(fp1,"\nThe next character is %c\n", (ch));
}
else if(ch ==122)
{
fprintf(fp1,"\nThe next character is a\n");
}
}
fclose(fp1);
fclose(fp);
}
