This article illustrates the use of C language variable types and output control, which is helpful for readers to summarize and conclude them. This example is Shared for your reference. The details are as follows:

The complete example code is as follows:

#include <stdio.h>
int main(void)
  int i1=024;     //The octal number begins with 0
  int i2=0xF0;    //Hexadecimal begins with 0x or 0x
  printf(" Octal number 024 Is the decimal value of: t%dn",i1);
  printf(" Hexadecimal number 0xF0 Is the decimal value of: t%dn",i2);
  double f1=1E1;
  double f2=0.3E1;
  printf("%.1f/%.1f = %-10.6lf|n",f1,f2,f1/f2);   //The line "|" is used to indicate the end position
  const float PI = 3.1415926535898f;
  printf("PI is: %.7fn",PI);
  char c1='a' , c2='b' ;
  printf(" test printf() The return value of the function n");
  printf("%dn",printf("%d",printf("%c%c",c1,c2))); //The return value of the printf() function is the number of output characters
  char ch1=0; //Initialize to null
  printf("Int The type and Char Type of ASCII Coding correspondence n");
  for(int i=0;i<128;i++)
  return 0;
