//第一个问题#include <>#define Pi #define AREA(x) (Pi*x*x)int main(){ int i=0; float a; for(i=1;i<=10;i++) { a=AREA(i); if(a>100) break; else printf("半径为%d的圆的面积是%f\n",i,a); }}//第二个问题#include <>#define Pi #define AREA(x) (Pi*x*x)void main(){ int i=0; float a; for(i=1;i<=15;i++) { a=AREA(i); if(a>50) printf("半径为%d的圆的面积是%f\n",i,a); }}//第三个问题#include <>void main(){ int i=0; for(i=1;i<=100;i++) { if(i%7) printf("%d不能被7整除\n",i); }}//第四个问题#include <>void main(){ int i=0; for(i=100;i>=1;i--) { if(!(i%13)) { printf("100以内整数中为13的倍数的最大值是:%d",i); break; } }}PS：基础知识扎实和不断的实践才能学好一门语言，也许一开始实践并不会那么的顺利，但等你独立思考解决了所有问题之后，你会感觉到这里面有无尽的乐趣的
