C program for creating a text file from string in buffer

Create a str_to_file.c file as contents below, OR use from github

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

int main (int argc, char **argv) {
    char *str = (char *) malloc(4096);
    FILE *fp;
    int ret;
    size_t size;

    strcpy(str, "{\"myname\":");
    strcat(str, "\"");
    strcat(str, "devbee");
    strcat(str, "\"}");

    fp = fopen( "myfile.txt" , "w" );
    size = fwrite(str , 1 , strlen(str) , fp);
    if (size != strlen(str)) {
         printf("unable to write to file: size: %d, strlen : %d\n", size, strlen(str));
    } else {
         printf("myfile.txt file written successfully\n");
    }

    fcolse(fp);
    free(str);

    return 0;
}

Compile above source as,

 $ gcc -o str_to_file str_to_file.c 

Test / Execute it as,

 $ ./str_to_file 

This will create myfile.txt in your current working directory where you have str_to_file binary,

The code is also available at github
