File Handling

Basic Syntax

FILE *file=fopen("xyx.txt","r/w/r+/w+/a");

if(!file)return printf("Error Msg"), 1;

.

.

.<<CODE>>>

.

.

fclose(file);

Red Color Highlight Meaning :

You Can Write As you Wish. Instead of file you can write suman,sabin, sunam etc, xyz.txt you can write abc.txt, xyz.doc etc.

File Creation

#include<stdio.h>
int main(){
    FILE *file=fopen("xyz.txt","w"); //here we are creating file                                             xyz.txt 
        if(!file) return printf("Tero File Sile Vetiyana, Ramro Sanga         Bana!");
        fprintf(file,"Hello Dasari!");//Content Here
        fprintf(file, "K cha tero Khabar?");
    fclose("file");
return 0;}

File Reading

Basic Syntax:

FILE *file=fopen("xyx.txt","r/w/r+/w+/a");

if(!file)return printf("Error Msg"), 1;

.

.

char line[];

fgets(line, sizeof(line),file);

printf("%s",line)

.

.

fclose(file);

Now Lets Demostrate

#include<stdio.h>

int main() {

    FILE *file = fopen("xyz.txt", "r");

        if(!file) return printf("error!"), 1;

        char line[100];

        fgets(line, sizeof(line), file);  // Read the first line

        printf("%s", line);               // Print it

    fclose(file);

return 0;

}
