C++ Read File Line by Line Into String
C Exercises: Read the file and shop the lines into an array
C File Handling : Practise-4 with Solution
Write a program in C to read the file and store the lines into an array.
Sample Solution:
C Lawmaking:
#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 = Naught; int i = 0; int tot = 0; printf("\n\n Read the file and store the lines into an array :\north"); 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]) - ane] = '\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("\due north"); render 0; } Sample Output:
Read the file and store the lines into an array : ------------------------------------------------------ Input the filename to exist opened : examination.txt The content of the file test.txt are : test line 1 test line 2 exam line 3 test line 4

C Programming: Tips of the Day
C Programming - What is the divergence between #include <filename> and #include "filename"?
In practice, the difference is in the location where the preprocessor searches for the included file.
For #include <filename> the preprocessor searches in an implementation dependent manner, normally in search directories pre-designated by the compiler/IDE. This method is ordinarily used to include standard library header files.
For #include "filename" the preprocessor searches first in the same directory every bit the file containing the directive, and and then follows the search path used for the #include <filename> form. This method is normally used to include programmer-defined header files.
