Question & Answer: Using for loop. What is the output for(int i=5; i>=0; i–) cout…..

program:

#include <iostream>

using namespace std;

int main()
{
int i; //loop variable
for(int i=5; i>=0; i–) //run for loop
{

cout<<“nvalue of is:”<<i; //prints i value
}

return 0;//return success
}

output:

Explanation:

from given for loop for(int i=5; i>=0; i–)

i intialized to 5 and check for condition whether i>=0 so here i=5 so

1st iteration: i prints 5  

then i become i– i.e 4

2nd iteration

:i check for condition whether >=0 , here i=4

so i prints 4

i–:3

3rd iteration:

here i=3 and check i>=0 yes so

i prints 3

now i– i.e 2

4th iteration: now i=2 and check whether i>=0 yes

so i prints value 2

then i– i.e 1

5th iteration: here i=1 so i>=0 condition true

so i prints value 1

then i– i.e 0

6th iteration: here i=0 condition i>0 true

so i prints value 0

then i– i.e -1

7th iteration: here i=-1 so check for condition i>=0 ,-1>=0 condition fails so loop will terminated
