Scanf exercise implementation
Exercise:
Write a Program which takes 6 characters (alphabets, numbers, and special characters) from the user and prints the ASCII codes of the entered characters.
First, create variables.
char c1, c2, c3, c4, c5, c6; //These are the variables to hold those characters.
After that, use the printf to send the message to the user.
printf(“Enter any 6 characters of your choice:”);
And after that, let’s use scanf to read the inputs. We are going to read 6 inputs, so 6 characters. The format specifier will be %c. Let’s give space after one format specifier. I mentioned the 6 format specifier here. After that &c1,&c2,&c3,&c4,&c5,&c6.
scanf(“%c %c %c %c %c %c”, &c1,&c2,&c3,&c4,&c5,&c6);
After that, let’s print the ASCII codes. ASCII code is a number, so which format specifier do you use to print a number. You can use %d (for signed integers) or %u(if it is unsigned). So, I can use %d or %u here, but I would use %u here because, anyway the codes are they are unsigned numbers.
Let me give \n at the beginning, type ASCII codes, and give the format specifier %u 6 times. After that, let’s print the value of these variables.
Printf(“\nASCII codes : %u,%u,%u,%u,%u,%u”,c1,c2,c3,c4,c5,c6);
The code is shown below.
#include<stdio.h>
int main(void)
{
char c1,c2,c3,c4,c5,c6;
printf("Enter any 6 characters of your choice :");
scanf("%c %c %c %c %c %c",&c1,&c2,&c3,&c4,&c5,&c6);
printf("\nASCII codes : %u,%u,%u,%u,%u,%u",c1,c2,c3,c4,c5,c6);
printf("\nPress enter key to exit the application \n");
while(getchar() != '\n')
{
//just read the input buffer and do nothing
}
getchar();
}
Output:
Enter any 6 characters of your choice, and I entered a space, b space, c space, d space, 1 space, and % sign. Press Enter key. It shows the ASCII codes of the entered characters(Figure 1). So, this is the correct result.
I want to give another assignment to you. So, modify this code. The output should be the same, but instead of using scanf use getchar().
