Write a C program to create a file

EX: Write a C program to create a file. How do you create file in file handling. C program to create file.

To learn file handling in C programming first we need to start from creating a file in C. To create a file in C there is a following syntax is used.

Syntax:

FILE *fp;

fp = fopen("file_name","mode");

In above syntax we declared file type pointer using structure FILE which is already declared in header file stdio.h. to and fopen() function is used to open a file.

Program to create a file in C:

#include<stdio.h>
int main()
{
    FILE *fp;
   
    fp = fopen("file.txt","w");
    /*Close file to release the
    allocated memory*/

    fclose(fp);
    return 0;
}

Above program will create a file in the same folder where your program file is saved.

We can also give a path to create a file at specific location.

#include<stdio.h>
int main()
{
    FILE *fp;
   
    fp = fopen("E:file.txt","w");
     /*Close file to release the
     allocated memory*/

    fclose(fp);
    
    return 0;
}

In next exercise we will learn how to write a content in a file.
