代码如下:
#include
#include
#define M 4
int add(int a, int b);
int sub(int a, int b);
int mul(int a, int b);
int div(int a, int b);
int (*oper_func[])(int, int) = {
add, sub, mul, div
};
char oper_sequence[M][10] = {
"add", "sub", "mul", "div"
};
int main()
{
char oper[10];
int seq;
int a,b;
int result;
int i;
printf("Operator:");
scanf("%s",oper);
printf("a:");
scanf("%d",&a);
printf("b:");
scanf("%d",&b);
for(i=0; i
