Put the code between [code] and [/code]

Could you copy and paste the actual error?

[ayndrew]

error expected unqualified-id before '{ ' token

on line 181 sorry, dont know y it changed

[Danny Toledo]

You have your semicolon in the wrong place:

float calcSphere( int radius ) //you had it here
{

    return 4 * PI * (radius*radius); //but it belongs here
}

You did that for a few functions.

Also, in your calcPyramid function, you have try to use height, but the argument's name is slantHeight:

float calcPyramid( int length, int slantHeight ); //int slantHeight and misplaced ;
{
    return ( 2 * length * height ) + (length*length) //height not defined
	
}

After fixing those errors, I got it to run.

[LB]

You have an extra semicolon at the end of line 179

[ayndrew]

still get same error at 181 :(

[LB]

Please repost your latest code.
