error: ‘for’ loop initial declarations are only allowed in C99 mode.

Some errors you might encounter when you compile with code::blocks.

error: 'for' loop initial declarations are only allowed in C99 mode

1	error: 'for' loop initial declarations are only allowed in C99 mode

One of many reasons is you have written code like:

for(int i=0;i&lt;=10;i++)
{}

1 2	for(int i=0;i<=10;i++) {}

To solve this error, just write code like this:

int i;
for(i=0;i&lt;=10;i++)
{}

int i;

for(i=0;i<=10;i++)

{}
