int main(){
FILE * fptr;
char c;
fptr=fopen("fgetcsample.txt","r");


printf("%c\n",fgetc(fptr));

store a table in dynamic array and then change the size of array dynamically to store more numbers

  #include <stdio.h> #include <stdlib.h> int main() {     int *ptr;     ptr = ( int *)malloc( 10 * sizeof ( int ));         printf( "The multiplication table of 7 is:\n" );     for ( int i = 0 ; i < 10 ; i++)     {         ptr[i]= 7 *i;         printf( "7 X %d = %d\n" ,i+ 1 ,ptr[i]);     }    ptr = realloc(ptr, 15 * sizeof ( int ));    printf( "\nThe multiplication table of 7 till 15 is:\n" );     for ( int i = 0 ; i < 15 ; i++)     {         ptr[i]= 7 *i;         printf( "7 X %d = %d\n" ,i+ 1 ,ptr[i]);     }     free(ptr);     return 0 ; }
