Examples of a C language

Title: 1,2,3,4 figures, the number of other with no repeat of the three-digit numbers can be composed? How much are?

Program analysis: can be filled in one hundred, ten digital bits are 1,2,3,4. Composition before removing all permutations arrangement conditions are not satisfied.

#include<stdio.h>
int main(){
   int i,j,k;
   printf("\n");
   for(i=1;i<5;i++){
       for(j=1;j<5;j++){
          for(k=1;k<5;k++){
               if(i!=j&&i!=k&&j!=k){
                    printf("%d,%d.%d\n",i,j,k);                 
       }
     }
   }
 }
}
