Answer:
Following are the program in C language
#include <stdio.h>// header file 
int main() // main function
{
 int x1,y1,z1; // variable declaration
 printf(" Enter the three number :");
 scanf("%d%d%d",&x1,&y1,&z1); // input the three number by user 
 printf(" Number 1:%d",x1); // dispaly number 2
 printf("\\");// move the control to next line
 printf(" Number 2:%d",y1);// dispaly number 2
 printf("\\");// move the control to next line
 printf(" Number 3:%d",z1);// dispaly number 3
return 0;
}
Output:
Enter the three number :12 23 45
 Number 1: 12
 Number 2: 23
 Number 3: 45
Step-by-step explanation:
In this program we have declared three variable x1, y1, z1 of type int .After that we take the input from user by using scanf function and finally printed the value on the three separate lines.
