Scanf Exercise<\/strong><\/span><\/span><\/p>\n

Write a program that takes 6 characters. Characters may be a combination of alphabets, numbers, or special characters. The program should take 6 characters from the user and prints the <\/span>ASCII<\/b><\/a> codes of the entered characters. <\/span><\/span><\/p>\n

This is how your output should look like, as shown in Figure 1.<\/span><\/p>\n

Figure 1. Output<\/span><\/figcaption><\/figure>\n

 <\/p>\n

First, there should be a message saying, “Enter 6 characters of your choice:”. <\/span><\/p>\n

Let’s enter some characters like alphabets, numbers, or special characters. Here I enter a b c d 1 2. So, enter the input by giving space in between. When I hit enter, it should print the ASCII codes, the equivalent ASCII codes of the characters. <\/span><\/p>\n

    \n
  1. Use scanf<\/strong> to read 6 characters from the user and store them in variables.<\/span><\/li>\n
  2. For each character, print its corresponding ASCII code by casting the character to an integer type.<\/span><\/li>\n<\/ol>\n

    The exercise requires you to write a C program that takes 6 characters as input from the user. These characters can be any combination of alphabets, numbers, or special characters. The program should then print the ASCII codes of the entered characters.<\/span><\/p>\n

    ASCII (American Standard Code for Information Interchange) is a character encoding standard used to represent text in computers and other devices that use text. Each character is assigned a unique numeric value (ASCII code), allowing computers to understand and manipulate text data.<\/span><\/p>\n

    To accomplish the task, you would need to use the scanf<\/strong> function in C to read the user’s input. The scanf<\/strong> function is used to read formatted input from the standard input stream (usually the keyboard). In this case, you would read 6 characters using scanf<\/strong> and store them in variables.<\/span><\/p>\n

    Once you have the characters stored, you can then use a loop or individual print statements to display the ASCII codes of each character. The ASCII code of a character can be obtained by simply casting the character to an integer type, as characters are internally represented as numeric values.<\/span><\/p>\n

    For example, if the user enters ‘A’, the ASCII code for ‘A’ is 65. If the user enters ‘1’, the ASCII code for ‘1’ is 49. (Figure 1)<\/span><\/p>\n

    Keep in mind that the ASCII codes of characters may vary based on the character encoding used by the system (e.g., ASCII or UTF-8). However, for standard ASCII characters, the codes will be consistent across most systems.<\/span><\/p>\n

    In the following article<\/a>, let’s implement this.<\/span><\/p>\n
