c ? operator
/* The expression a ? b : c evaluates to b if the value of a is true,
* and otherwise to c
*/
// These tests are equivalent :
if (a > b) {
result = x;
}
else {
result = y;
}
// and
result = a > b ? x : y;c ? operator
/* The expression a ? b : c evaluates to b if the value of a is true,
* and otherwise to c
*/
// These tests are equivalent :
if (a > b) {
result = x;
}
else {
result = y;
}
// and
result = a > b ? x : y;C logical operators
1. && (AND) is true when both the conditions are true
“1 and 0” is evaluated as false
“0 and 0” is evaluated as false
“1 and 1” is evaluated as true
2. || (OR) is true when at least one of the conditions is true. (1 or 0 = 1)(1 or 1 = 1)
3. ! returns true if given false and false if given true.
!(3==3) evaluates to false
!(3>30) evaluates to truec ? operator
? : Conditional Expression operator
If Condition is true ? then value X : otherwise value Y
y = x==0 ? 0 : y/xc |= operator
// | is the binary "or" operator
// a |= b is equivalent to a = a|b
#include <stdio.h>
int main() {
int a = 10; // 00001010 in binary
int b = 6; // 00000110 in binary
printf("Result : %dn", a |= b);
// Result is 14 which is OOOO111O in binary
return 0;
