Write a program that displays  David says, “programming is fun!”<\/span>. The goal was to print a text or a string in double-quotes. <\/span><\/strong><\/p>\n

 <\/p>\n

Solution<\/strong><\/span><\/p>\n

When you use <\/span>printf<\/b>, you should always write your message inside the double-quotes; you should remember that. And our string was, <\/span>“David says, “programming is fun!” “<\/b>. This is our message. Now let’s terminate the statement with a semicolon. <\/span><\/span><\/p>\n

Let’s run this. Here you met with some errors(Figure 1). So, let’s check the error.<\/span><\/p>\n

\"Figure
Figure 1. Exercise<\/span><\/figcaption><\/figure>\n

 <\/p>\n

Error is expected ‘<\/span><\/span>)’<\/b><\/span> before ‘programming’. So, inserting a bracket before programming is not correct, that’s not what we wanted.<\/span><\/span><\/p>\n

Here we are confusing the compiler by giving too many double-quotes. If you want to print a double quote, you have to use the associated escape sequence. <\/span><\/p>\n

So, we have to tell the compiler to consider a double quote as a normal character; otherwise, the compiler will consider it the beginning of the printf statement. So, we tell that by using the escape character. Our escape character is, you know, that is a <\/span>backslash<\/b>. Now we are to take the help of backslash. Give the backslash before the double quote, as shown in Figure 2. <\/span><\/span><\/p>\n

When you give the backslash before the double quote, the letter or character will be considered a normal printable character.<\/span><\/p>\n

And after that, let’s give \\n to go to the following line, and here let’s print <\/span>\u201cGood day !\u201d<\/b>.<\/span><\/span><\/p>\n

 <\/p>\n

\"Printf
Figure 2. Using backslash double quote (\\\u201d)<\/span><\/figcaption><\/figure>\n

 <\/p>\n

From this article, you should understand that you have to use this escape sequence: <\/span>backslash double quote(\\\u201d)<\/b> to print a double quote. <\/span><\/span><\/p>\n

 <\/p>\n

Now, if you want a single quote, then you can use a <\/span>backslash single quote(\\\u2019)<\/b>, no problem, as shown in Figure 3. <\/span><\/span><\/p>\n

Let’s run. You can see that it has been printed with a single quote.<\/span><\/p>\n

\"Printf
Figure 3. Using backslash single quote (\\\u2019)<\/span><\/figcaption><\/figure>\n

 <\/p>\n

Or you can omit the backslash and only use single quotes, no problem with that. So, both are the same. And it should work fine, shown in Figure 4.<\/span><\/p>\n
