B+

B+ is a C and GLSL-based esolang made by User:Cordership.

Syntax

Basics

Declaring variables

make var_type var_name;

A variable can be an integer, a float, a double, or a string.

Assigning values

varf(format_specifier, var_name, var_value)

It can be a string (%s), an integer (%d), or a float (%f).

STDIO

Output by the printf() function:

#include <stdio>
main() {
    printf("Whatever you want");
    exit 0;
}

Assign input to a variable using getinp (reads the full input):

#include <stdio>
main() {
    make str a;
    getinp("%s", a);
}

Cat program:

#include <stdio>
main() {
    make str a;
    getinp("%s", a);
    printf(a);
    exit 0;
}

Operators

The order of operators is the same as C.

Precedence	Operator	Description	Associativity
1	++ --	Postfix increment and decrement	Left-to-right
	()	Function call
	[]	Array subscripting
	.	Structure and union member access
	->	Structure and union member access through pointer
	(type){list}	Compound literal
2	++ --	Prefix increment and decrement	Right-to-left
	+ -	Unary plus and minus
	! ~	Logical NOT and bitwise NOT
	(type)	Cast
	*	Indirection (dereference)
	&	Address-of
	count	Size-of in elements
	sizeof	Size-of
	_Alignof	Alignment requirement
3	* / %	Multiplication, division, and remainder	Left-to-right
4	+ -	Addition and subtraction (Addition is concatenation if both sides are strings)
5	<< >>	Bitwise left shift and right shift
6	< <=	For relational operators < and ≤ respectively
	> >=	For relational operators > and ≥ respectively
7	== !=	For relational = and ≠ respectively
8	&	Bitwise AND
9	^	Bitwise XOR (exclusive or)
10	|	Bitwise OR (inclusive or)
11	&&	Logical AND
12	||	Logical OR
13	?:	Ternary conditional	Right-to-left
14	=	Simple assignment
	+= -=	Assignment by sum and difference
	*= /= %=	Assignment by product, quotient, and remainder
	<<= >>=	Assignment by bitwise left shift and right shift
	&= ^= |=	Assignment by bitwise AND, XOR, and OR
15	,	Comma	Left-to-right

If-else

1-branch:

#include <stdio>
main() {
    if (condition) {
        //code;
}

2-branch:

#include <stdio>
main() {
    if (condition) {
        //code;
    } else {
        //code;
}

Multiple if-then-elses:

#include <stdio>
main() {
    if (cond1) {
        //code;
    // } else if (cond2) {...

Ternary operator:

#include <stdio>
main() {
    make int a, make int b;
    getinp("%d", "%d", a, b);
    make int max;
    varf("%d", max, (a < b) ? b : a);
    printf("The largest number is %d", max);
    exit 0;

Loops

For loop:

for (cond1; cond2; cond3;…) {
    //code
}

While loop:

while (cond) {
    //code

Arrays

In B+, arrays are the same as C. They must be the same data type. To assign the value of an array, the same format specifier for its elements are used. For example,

make array n;
varf("%d", n, {0, 1, 2, 5})

There are matrices too.

make matrix n;
varf("%d", n, {{0, 1, 2}, {1, 2, 3}}

The sizeof function returns the size of an array using bytes, while the count function returns the number of elements in an array.

Functions

In B+, functions are defined almost the same way as C.

#include <stdio>
float f(float n) {
    exit 0;
}
