Need help compiling in C: lvalue required as left operand of assignment
Hi,
I am trying to compile a program (not coded by me), and i'm getting this error:
As you may be guessing, the program doesn't compile, the line number 203 is the following:
What am i missing? what's wrong here?

When i tyr this, it gives me a syntax error...i tried removing quotes,removing spaces,replacing -eq with '='.. Can somebody suggest that is the problem?

Does anyone know what is wrong here?

Hey all. I've been working on some fun with C and decided to write a Rock Paper Scissors game. The problem is, that when I try to compile the file, it gives "lvalue required as left operand of assignment" error. The error line is here:

Hi,
This code was originally to print a sine function table. I modified it to print a tangent function table. I got an "lvalue" error which I can't solve...Any hint on why am I getting this error?

Hi I'm new to shell programming. How do I extract the size of an operand in a simple instruction in a C program? Lets say there is an addition a+b somewhere in a C code where a and b are integers. How to extract the size of a & b in bits? Is there something called intermediate code before an... (4 Replies)
When I create a bootable Linux distro installation USB drive, I use this command: sudo dd if=/Path/to/linux_distro.iso of=/dev/rdisk<disk number>

When I look it up, I've seen variations of people choosing 4M, and I think 8M, 2M, and maybe even 1M.
If I leave the operand... (4 Replies)

__alignof__
__ALIGNOF__(3) BSD Library Functions Manual __ALIGNOF__(3)NAME
__alignof__ -- GNU extension for alignment of an object
SYNOPSIS
int
__alignof__(void x);
DESCRIPTION
The __alignof__() operator returns the alignment of its operand. The operand can be a type or an expression. If the operand is a 'lvalue',
the return value represents the required alignment of the underlying type, not the actual alignment of the specified 'lvalue'.
The returned value is specific to the architecture and the ABI. If the architecture does not impose strict alignment requirements,
__alignof__() returns the minimum required alignment. If __aligned(3) is used to increase the alignment, __alignof__() returns the specified
alignment.
EXAMPLES
The syntax is comparable to the sizeof() operator. If the architecture aligns integers along 32-bit address boundaries, the following should
print the value 4.
(void)printf("%d
", __alignof__(int));
On the other hand, the following example should print the value 1, even though this is unlikely to be the actual alignment of the structure
member.
struct align {
int x;
char y;
} a;
(void)printf("%d
", __alignof__(a.y));

This is a non-standard, compiler-specific extension.
