This document summarizes the most commonly used functions within C, with name, way of programming and output. NOTE: some parts may be Dutch, but the programming stays the same nontheless.

shifting shift left ( a << b) shift right ( a >> b)
a << 1 is gelijk aan a * 2 a >> 1 is gelijk aan a / 2
voorbeeld: 00001010 << 2 = 00101000 (dec. 10 -> dec. 40)
compound In C geldt: a += b; is hetzelfde als: a = a + b;
assignment Zo ook: a &= b; is hetzelfde als: a = a & b;
operator
Overzicht alle operatoren:
bit operatie byteValue |= 1 << 2; // set bit 2 op 1
byteValue &= ~(1 << 2); // set bit 2 op 0
print number void print_0_to_15() { 0= 0000 8= 1000
char i; 1= 0001 9= 1001
with bitwise for (i=0; i<=15; i++) { 2= 0010 10= 1010
operation printf("%2d= ", i); 3= 0011 11= 1011
print_char_binair(i); 4= 0100 12= 1100
printf("\n"); 5= 0101 13= 1101
} 6= 0110 14= 1110
} 7= 0111 15= 1111

pointer int i = 8; // integer i met waarde 8
int *p; // pointer naar een integer /* - int i krijgt random adres 268

printf("%d", *p); // print inhoud waar - *p = inhoud i (* heft & op)
