classical algorithm c language program 1】 【Title: There are numbers 1,2,3,4, how many can be composed of distinct three-digit numbers with no repetition? Is how much? 1. Program Analysis: fill in the hundred, ten, a bit of the numbers are 1,2,3,4. Removed after the composition does not satisfy all the conditions of the arrangement of the arrangement. 2. Program source code: main () {int i, j, k printf (" \ n" ) for (i = 1 i < 5 i++) /* The following is the triple loop*/for (j = 1 j < 5 j++) for (k = 1 k < 5 k++) {if (i! = k & & i! = j & & j! = k) /* ensure i, j, k three distinct*/printf ( " d, d, d \ n" , i, j, k) }}
