This is C PROGRAMMING

#include

int main(int argc, const char * argv[]) {

{

FILE *infile;

char c;

infile = fopen ("test.in", "r");

if (infile == NULL)

{

printf ("Could not open file test.in ");

return 1;

}

while (! feof(infile) )

{

c = getc(infile);

if ( !isdigit (c) )

putchar(c);

} /* end while */

return 0;

} /* end main */

}

Please make the following assumption:

File test.in exists and contains the following data:

J2A3ME4S5 4B2O0N78D90

( Note the only space in the above data is between the 5 and the 4.)
