    question about an incrimenting method in for loop

    Hello,
    I'm new to programming and when i was creating a simple program which prints a set of numbers, I incremented the for loop as x=+1 but when I executed this, 1 was written again and again without an end of execution, does anyone have an idea on what might be wrong.
    below is the code for reference, Also I'm using Bcc 5.5 compiler

    Code:
    #include<stdio.h>
    #include<math.h>
    void main()
    {
    	int x;
    	x=0;
    	for(x=0;x<10;x=+1)
    	{
    		if (x==5)
    		break;
    		printf ("%d\n", x);
    	}
    }

    Clearly you meant +=, not =+. Also, main() should be defined as int main(void) and must return 0.

    		break;
    		printf ("%d\n", x);
    	}
    }
    What you wrote... for(x=0;x<10;x=+1)
    How the compiler saw it... for(x=0;x<10;x=(+1))

    When setting up your source code use some spacing...
    Code:
    for ( x = 0; x < 10; x += 1 )
    It makes no difference to the compiler but it makes mistakes a whole lot easier for us humans to spot.
