Question

1. Set up a for loop to print values from n down to 1 with at most 5 values per line. For example, when n is 7 then the output is shown below:

7    6    5    4    3
2    1

C++ code

Answer 1

C++ code:

#include <iostream>
using namespace std;
int main(){
//initializing count and giving a sample value for n
int count=0,n=7;
//looping from n to 1
for(int i=n;i>=1;i--){
//incrementing count
count++;
//checking if count is not 5
if(count!=5)
//printing current number i
cout<<i<<" ";
else{
//initializing count as 0
count=0;
//printing i and ending line
cout<<i<<endl;
}
}
return 0;
}
