1、打開(kāi)CodeBlocks,新建一個(gè)空白文件,先定義頭文件和主函數(shù),接著寫(xiě)程序多大的主體:2、首先定義所需要的變量,將變量定義為浮點(diǎn)型,定義輸入函數(shù),將剛才的x和y定義為計(jì)算的變量,將c定義為選擇計(jì)算方式的變量。用switch語(yǔ)句,將c作為選擇變量,填寫(xiě)計(jì)算方式的選項(xiàng),最后在主函數(shù)中輸入一個(gè)輸出函數(shù)來(lái)...
include<stdio.h>int main(){float a,b,c,d;scanf("%f %f",&a,&b);//輸入長(zhǎng)和寬c=a*b;d=2*(a+b);printf("S=%.2f L=%.2f\n",c,d);//S是面積,L是周長(zhǎng)return 0;}
下面是使用 C 語(yǔ)言設(shè)計(jì)簡(jiǎn)易科學(xué)計(jì)算器的示例代碼:include <stdio.h> include <stdlib.h> include <math.h> int main(){ char op;double num1, num2;printf("請(qǐng)輸入數(shù)學(xué)表達(dá)式(如:1 + 2):");scanf("%lf %c %lf", &num1, &op, &num2);switch (op){ case '+':printf("結(jié)果...
}else if(answer==0){ printf("***模擬計(jì)算器結(jié)束***\n");}else{ printf("輸入錯(cuò)誤,請(qǐng)重新輸入!\n\n");ask(numA,numB);} } void main(){ printf("*21級(jí)1班,小組成員,姓名:姓名,姓名*\n\n\n");printf("***模擬計(jì)算器開(kāi)始***\n\n");int numA,numB;printf("請(qǐng)輸入兩個(gè)運(yùn)...
標(biāo)準(zhǔn)答案:void main(){ float a,b;char c;printf("Please enter your math;");scanf("%d%c%d",&a,&c,&b);switch(c){case'+':printf("a+b=%f\n",a+b);break;case'-':printf("a-b=%f\n",a-b);break;case'*':printf("a*b=%f\n",a*b);break;case'/':{if(b!=0)...
