#include main { int data1,data2,a; char op; switch(op) case"_" a = data1 - data2; break; case"+" a = data1 + data2; break; case"*" a = data1* data2; break; case"/" a = data1 / data2; break; }
回答2：
int result = 0; switch (op) { case "+": result = data1 + data2; break; case "-": result = data1 - data2; break; case "*": result = data1 * data2; break; case "/": result = data1 / data2; break; }
