expression containing logical operator returns either 0 or 1 depending upon whet
expression containing logical operator returns either 0 or 1 depending upon whether expression results true or false. Logical operators are commonly used in decision making in C programming.
Program:
#include
#include
void main()
{
int a = 5, b = 5, c = 10, result;
clrscr();
result = (a == b) && (c > b);
printf(“(a == b) && (c > b) is %d n”, result);
result = (a == b) && (c < b);
printf("(a == b) && (c < b) is %d n", result);
result = (a == b) || (c < b);
printf("(a == b) || (c < b) is %d n", result);
result = (a != b) || (c < b);
printf("(a != b) || (c < b) is %d n", result);
result = !(a != b);
printf("!(a != b) is %d n", result);
result = !(a == b);
printf("!(a == b) is %d n", result);
getch();
}
Output :
(a == b) && (c > b) is 1
(a == b) && (c < b) is 0
(a == b) || (c < b) is 1
(a != b) || (c < b) is 0
!(a != b) is 1
!(a == b) is 0
