C语言编程题:输入两个整数,计算并用浮点数显示其和,差以及相除的...答:include <stdio.h> include <stdlib.h> int main (){ int a,b;printf ("input 2 int data: ");scanf ("%d %d",&a,&b);printf("\n");printf("%d + %d = %f\n",a,b, (float)(a+b));printf("%d - %d = %f\n",a,b, (float)(a-b));// printf("%d * %d = %f\...
c语言 两个循环同时作用怎么写答:最简单方法就是把上面的数 放在两个数组里面,一个循环就可以输出了。int a[]={1,2,3,4,5};int b[]={5,4,3,2,1};int i=0;for(i=0;i<5;i++){ printf("%f,",a[i]/b[i]);}
C语言:请编写一个程序,从键盘读入两个整数a和n,计算并输出a+aa+aaa+...答:include <stdio.h> void main(){int i,j,a,n,k=0,out=0;printf("请输入a与n:");scanf("%d %d",&a,&n);for(i=0;i<n;i++){ for(j=0;j<=i;j++){ k=k*10+a;} out+=k;k=0;} printf("the result is:%d\n",out);} 或者用楼上的公式 include <stdio.h> void ...
c语言程序,怎样判断两个字符串相等并且输出相同的那个结果?答:3 = 2 + 1 char d[11]={'0','1','2','3','4','5','6','7','8','9'};for (int i=0; i<10; i++)for (int j=0; j<10; j++) { char e[3] = { d[i], d[j] };if (strcmp(e,c)==0)printf("密码运算成功!密码为%s\n", e);} } ...
