C Exercises: Read the file and store the lines into an array

C File Handling : Exercise-4 with Solution

Write a program in C to read the file and store the lines into an array.

Sample Solution:

C Code:

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

#define LSIZ 128 
#define RSIZ 10 

int main(void) 
{
    char line[RSIZ][LSIZ];
	char fname[20];
    FILE *fptr = NULL; 
    int i = 0;
    int tot = 0;
    printf("\n\n Read the file and store the lines into an array :\n");
	printf("------------------------------------------------------\n"); 
	printf(" Input the filename to be opened : ");
	scanf("%s",fname);	

    fptr = fopen(fname, "r");
    while(fgets(line[i], LSIZ, fptr)) 
	{
        line[i][strlen(line[i]) - 1] = '\0';
        i++;
    }
    tot = i;
	printf("\n The content of the file %s  are : \n",fname);    
    for(i = 0; i < tot; ++i)
    {
        printf(" %s\n", line[i]);
    }
    printf("\n");
    return 0;
}

Sample Output:

 Read the file and store the lines into an array :                                                            
------------------------------------------------------                                                        
 Input the filename to be opened : test.txt                                                                   
                                                                                                              
 The content of the file test.txt  are :                                                                      
                                                                                                              
 test line 1                                                                                                  
 test line 2                                                                                                  
 test line 3                                                                                                  
 test line 4

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.
