Output (Print Text)
To output values or print text in C, you can use the printf() function:
Example
#include <stdio.h>
int main() {
printf("Hello World!");
return 0;
}
Double Quotes
When you want to print text, the text must be wrapped in double quotes "".
If you forget the double quotes, an error occurs:
Example
printf("This sentence will work!");
Tip: If you see strange error messages, check that your text starts and ends with double quotes.
Many printf() Functions
You can use as many printf() functions as you want.
However, note that it does not insert a new line at the end of the output:
Example
#include <stdio.h>
int main() {
printf("Hello World!");
printf("I am learning C.");
printf("And it is awesome!");
return 0;
}
Note: Notice: All the text appears on the same line. In the next chapter, you will learn how to add new lines to make the output easier to read.
