I need some help to rewrite the feof while loop to a for loop in c.
I don't understand how to make the while loop to a for loop where it is commented feeding the matrix
I have two variables n and m.
Variable n is the size of the array / 1023 in rows and m is columns that are 1023 in size.
#include <stdio.h>
#include <stdlib.h>
int main()
{
int n, m;
int **A;
FILE *inputFile;
inputFile = fopen("Input.dat", "r");
if (inputFile == NULL){
printf("An error occured while reading the file");
exit(1);
}
fscanf(inputFile, "%d%d", &n, &m);
A = (int **)malloc(n * sizeof(int *));
if (A == NULL){
printf("An error occured while allocating");
exit(1);
}
// allocating memory to the matrix.
for (int i = 0; i < n; i++){
A[i] = (int *)malloc(m * sizeof(int));
}
// feeding the matrix.
for (int i = 0; i < n; i++){
if (feof(inputFile)){
break;
}
for (int y = 0; y < m; y++){
if (!feof(inputFile)){
fscanf(inputFile, "%d", &A[i][y]);
}
else{
break;
}
}
}
// print out the 2D array
int Max = A[0][0];
for (int i = 0; i < n; i++){
printf("\n");
for (int j = 0; j < m; j++){
printf("%d\t", A[i][j]);
if (Max < A[i][j]){
Max = A[i][j];
}
}
}
printf("\nThe biggest number in the matrix is: %d", Max);
// freeing memory and closing file
free(A);
fclose(inputFile);
return 0;
}
