[Solved] What is the error in this code please help:

by


Let’s look at each error in you code.

Firstly

x=o;

Did you mean 0 ( zero ) or a variable o or the character 'o'.
If it was 0 ( zero ) or 'o' ( character ) or a variable ( having a value greater than or equal to 10 ) , then the loop will not run even once because of the condition

while (x < 10);

If o was a variable ( and it’s value is less than 10 ), then it will be an infinite loop because you left a semicolon after the while loop.
If there were no semicolon after the while loop, then the loop would have executed until the condition x < 10 returns false.

Next

for (i= .2; i =3; i++)
cout << "i = ";
cout << i;

Firstly, is there supposed to be {} here and maybe the actual code you meant was

for (i= .2; i =3; i++)
{
cout << "i = ";
cout << i;
}

If there are no braces {} , then only the first line, that is cout << "i = "; would be executed under the for loop ( it would be an infinite loop unless you change the for loop condition ) .

Also, did you mean .2 or 2 ( they are different )

Next, if i was a float ( or int ), then this would be an infinite loop because the condition in your for loop is i = 3. That assigns the value 3 to i and it will return true, and hence, the loop will be an infinite loop.

If the condition was changed to something like i == 3 ( it will iterate 0 times ) or i < 3 ( it will iterate 1 time ) , then it will work.

If i was an int, then all the values after the decimal will be skipped and initially, i will have the value 0 and not 0.2, but it would still be an infinite loop unless you change the conditions as mentioned before.

But, if you change it to i < 3, then it will iterate 3 times ( because i will get the values 0,1, and 2 )

Well, these are the errors in your code. Now, the code may differ depending on your original intention, but here are some examples

int x = 0;
while (x < 10)
    x++;

Result
x will have the value 10 after the loop ends.

Next code

int i;
for ( i = 2 ; i < 3 ; i++ )
  {
    cout << "i = ";
    cout << i;
  }

OUTPUT

i = 2
