1.1-100之间的素数

#include<stdio.h>

void main(){

         inti,j;

         printf("1-100之间的素数有:\n");

         for(i=2;i<=100;i++){

                  inttemp=1;

                  for(j=2;j<i;j++){

                          if(i%j==0){

                                   temp=0;

                                   break;

                  }

                  }

                          if(temp==1)

                                   printf("%d",i);

}

}

2.求m,n的最小公倍数

#include<stdio.h>

void main(){

 intm,n,max;

 scanf("%d%d",&m,&n);

 if(m>=n){

          max=m;

          if(max%m==0 && max%n==0){

                   printf("%d\n",max);

          }

          else{

                   max=m*n;

                   printf("%d\n",max);

 }

 }

 if(m<n){

          max=n;

          if(max%m==0 && max%n==0){

                   printf("%d\n",max);

          }

          else{

                   max=m*n;

                   printf("%d\n",max);

 }

 }

}
