The ReadLine and FetchLine functions, below, are equivalent,
but their parameter declarations are appropriate for
their intended use

#include <stdio.h>
int ReadLine ( char str[], int n ) {
int ch;
int i = 0;

while ( (ch = getchar()) != '\n' ) {
if ( i < n ) {
str[i] = ch; i++;
}
}
str[i] = '\0';
return (i);

}

int FetchLine (char* str, int n) {
int ch;
int i = 0;

while ( (ch = getchar()) != '\n' ) {
if ( i < n ) {
*(str+i) = ch; i++;
}
}
*(str+i) = '\0';
return (i);
}
The functions are used in the following way:
