Chapter 6 ■ Characters
H
This would print
on a line by itself. We could, of course, label our output as in the following statement:
printf("The first character is %c \n", ch);
This would print
The first character is H
Finally, we don’t even need ch. If all we want to do is print the first character in the data,
we could do so with:
printf("The first character is %c \n", getchar());
If we want to print the numeric code of the first character, we could do so by using the
specification %d instead of %c. These ideas are incorporated in Program P6.1.
Program P6.1
//read the first character in the data, print it,
//its code and the value of EOF
#include <stdio.h>
int main() {
printf("Type some data and press 'Enter' \n");
char ch = getchar();
printf("\nThe first character is %c \n", ch);
printf("Its code is %d \n", ch);
printf("Value of EOF is %d \n", EOF);
}
The following is a sample run:
Type some data and press 'Enter'
Hello
The first character is H
Its code is 72
Value of EOF is -1
146
