In C language, what is the ending character of a simple statement?

In C language, the terminator of a simple statement is: semicolon (;). Statements in C language are divided into simple statements and compound statements. Simple statements are marked with a semicolon ";" as the end mark, and "}" is used as the end mark of the statement.

Statements in C language are divided into simple statements and compound statements.

Simple statements end with a semicolon (;). Among the simple statements, there are assignment statements, declaration statements, structured statements, function call statements and empty statements. Compound statements refer to using curly braces {} to wrap simple statements or even other compounds, so } is used as the end mark of a statement.

Examples are as follows:

printf("HelloWorld")   // 不加分号，在编译的时候会报错
printf("HelloWorld");  // 编译的时候不会报错，输出HelloWorld

It should be noted that macro definitions do not require semicolons, such as:

#define PI 3.14   // 不用加分号，加了分号会报错
