Please download in the following format~ [Program 1] Title: With 1, 2, 3, and 4 numbers, how many three-digit numbers can be formed that are different from each other and have no repeating numbers? How much are they? 1. Program analysis: The numbers that can be filled in the hundreds, tens, and ones are 1, 2, 3, and 4. After the placement that constitutes everything, the placement that does not meet the conditions is removed. 2. Program source code: main(){inti,j,k;printf(\n);for(i=1;ilt;5;i )/
The following is a triple loop
/for(j=1;jlt;5;j )for(k=1;klt;5;k ){if(i!=ki!=jj!=k)/
Make sure that i, j, and k are different from each other
/printf(
n,i,j,k);}}This document includes the following attachments:
