C Exercises: Create a file and input text

C File Handling : Exercise-1 with Solution

Write a program in C to create and store information in a text file.

Sample Solution:

#include <stdio.h>
#include <stdlib.h>
  
int main()
{
   char str[1000];
   FILE *fptr;
   char fname[20]="test.txt";

    printf("\n\n Create a file (test.txt) and input text :\n");
	printf("----------------------------------------------\n"); 
   fptr=fopen(fname,"w");	
   if(fptr==NULL)
   {
      printf(" Error in opening file!");
      exit(1);
   }
   printf(" Input a sentence for the file : ");
   fgets(str, sizeof str, stdin);
   fprintf(fptr,"%s",str);
   fclose(fptr);
   printf("\n The file %s created successfully...!!\n\n",fname);
   return 0;
}

Sample Output:

 Create a file (test.txt) and input text :                                                                    
----------------------------------------------                                                                
 Input a sentence for the file : This is the content of the file test.txt                                     
                                                                                                              
 The file test.txt created successfully...!!

C Programming: Tips of the Day

What is the size of an enum in c?

An enum is only guaranteed to be large enough to hold int values. The compiler is free to choose the actual type used based on the enumeration constants defined so it can choose a smaller type if it can represent the values you define. If you need enumeration constants that don't fit into an int you will need to use compiler-specific extensions to do so.
