Concept understanding — Assignment, Increment and Conditional Operators in C

Beyond the basic arithmetic and relational operators, C offers several operators that make code shorter and more expressive.

Assignment and compound-assignment operators. The simple = stores a value in a variable. C also provides compound forms that combine an operation with assignment: +=, -=, *=, /=, %= and the bitwise ones such as ^=. For example, x += y is a compact way of writing x = x + y, and x ^= y means x = x ^ y. These give a neat, compact representation of arithmetic and bit operations.

Increment and decrement operators. The increment operator ++ adds 1 to a variable and the decrement operator -- subtracts 1. Each has two forms: the prefix form (++a) changes the value before it is used in the expression, while the postfix form (a++) uses the current value first and changes it afterwards. …

[!TLDR]

Compound assignment operators (+=, -=, *=, /=, %=) give a compact way of writing a = a op b.

C allows an arithmetic operator and the assignment operator to be combined into a single compound (shorthand) operator. Thus a += b means a = a + b, and similarly for -=, *=, /= and %=. The program demonstrates each on the same variable.

#include <stdio.h>
int main()
{
    int a = 10, b = 3;
    a += b;   printf("a += b : a = %d\n", a);   /* a = a + b */
    a -= b;   printf("a -= b : a = %d\n", a);   /* a = a - b */
    a *= b;   printf("a *= b : a = %d\n", a);   /* a = a * b */
    a /= b;   printf("a /= b : a = %d\n", a);   /* a = a / b */
    a %= b;  printf("a %= b : a = %d\n", a);  /* a = a % b */ …
