    #include<stdio.h>

    #include<stdlib.h>

    int plus(int a,int b){

    return a+b;

    }

    int minus(int a,int b){

    return a-b;

    }

    int multi(int a,int b){

    return a*b;

    }

    double equal(int a,int b){

    return (double)a/b;

    }

    int main(void){

    int a,b;

    int P,M,X;

    double E;

    printf("請輸入兩個整數(ex : 1 2) : ");

    scanf("%d %d",&a,&b);

    P = plus(a,b);

    M = minus(a,b);

    X = multi(a,b);

    E = (double)equal(a,b);

    printf("和 : %d 差 : %d 積 : %d 商 : %.2f",P,M,X,E);

    system("pause");

    return 0;

    }
