Extended data:

Usage of printf () function:

The calling format of the printf () function is: printf(" &；; lt； Format string &; gt； ”，& amplt； Parameter table &; gt； )。

The formatted string consists of two parts: one part is normal characters and will be output as it is; The other part is to format the specified characters, starting with "%"followed by one or several specified characters, which is used to determine the format of the output content.

Parameter list is a series of parameters to be output, and its number must be as much as the number of output parameters described in the formatted string. The parameters are separated by ",",and the order is one-to-one, otherwise unexpected errors will occur.

For example:

int a = 6789

printf("a=%d\n "，a)；

The output result is a=6789.
