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("[Output]n");
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("n[Output]n");
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("n[Output]n");
printf("PI is: %.7fn",PI);
char c1='a' , c2='b' ;
printf("n[Output]n");
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("n[Output]n");
printf("Int The type and Char Type of ASCII Coding correspondence n");
printf("tInttCharn");
printf("t----t----n");
for(int i=0;i<128;i++)
{
ch1=i;
printf("t%dt%cn",i,ch1);
}
return 0;
}
