Extended information

contains the data to be output, which can be constants (character constants, numeric constants, string constants), variables, and calculation expressions. The data here should correspond one-to-one with the format control characters in the previous format (an error will occur if they do not correspond).

For example:

int?a=1;float?b=1.0;

char?str[12]="Hello?World";printf("This?is?an? example?of?printf:\n");

printf("a?is?%d,b?is?%f,and?a+b=%f",a,b,a +b);printf("I?want?to?say,%s",str);
