要打印变量的内容,请使用printf()
函数并指一些新格式选项。
#include <stdio.h>
int main()
{
//variable declarations
int x;
float y;
char c;
//variable initializations
x = -1234;
y = 123.12;
c = 'M';
//printing variable contents to standard output
printf("\nThe value of integer variable x is %d", x);
printf("\nThe value of float variable y is %f", y);
printf("\nThe value of character variable c is %c\n", c);
}
