C Program to read array from file in C

Read integer array from File in C

this require 2 files:
1) f.txt : which our array is stored
Data:

1 2 3 4 5 6 7 7 8 9

1 2 3 4 5 6 7 7 8 9

1 2 3 4 5 6 7 7 8 9

1 2 3 4 5 6 7 7 8 9

1 2 3 4 5 6 7 7 8 9

2) Programe file : where code resides

Code:

#include<stdio.h>

void main()

{

FILE *f; 

int R=0,C=0,No_OF_COLUMN=0; //Store Row and Column pointer

int i=0,j=0; //Temperory variable

int ARR[100][100]; //Final array where values to be stored

char ch,c[10];

f=fopen("f.txt","r");

while((ch=(char)fgetc(f))!=EOF)

{

if(ch==' ' )

{

c[i]='\0';

ARR[R][C]=atoi(c); // store value into array

i=0;

C++;//Increament Column pointer

if(No_OF_COLUMN<C)

{

No_OF_COLUMN=C;

}

}

else if(ch == '\n')

{

c[i]='\0';

ARR[R][C]=atoi(c); // store value into array

i=0;

C=0; //reset Column pointer

R++; //increament Row pointer

}

else

{

c[i]=ch;

i++;

//printf("%c",ch);

}

}

fclose(f);

for(i=0;i<R;i++)

{

for(j=0;j<No_OF_COLUMN;j++)

{

printf(" %d ",ARR[i][j]);

}

printf("\n");

}

}

Output:

1 2 3 4 5 6 7 7 8 9

1 2 3 4 5 6 7 7 8 9

1 2 3 4 5 6 7 7 8 9

1 2 3 4 5 6 7 7 8 9

1 2 3 4 5 6 7 7 8 9
