C语言基础：自增自减符号位置的区别，– a和a–的区别演示
#include <stdio.h>
int main ()
{
int value = 1;
printf("Using postfix %d\n", value--);
printf("Value after decrement %d\n", value);
value = 1;
printf("Using prefix %d\n", --value);
printf("Value after decrement %d\n", value);
return 1;
}
gcc编译运行结果
Using postfix 1 Value after decrement 0 Using prefix 0 Value after decrement 0
自增代码
#include <stdio.h>
int main ()
{
int value = 1;
printf("Using postfix %d\n", value++);
printf("Value after increment %d\n", value);
value = 1;
printf("Using prefix %d\n", ++value);
printf("Value after increment %d\n", value);
return 1;
}
gcc编译运行结果
Using postfix 1 Value after increment 2 Using prefix 2 Value after increment 2
