What does! = mean in programming?
In programming, != is an operator used to test for inequality. It is read as "not equal to." The != operator evaluates to true if the two operands are not equal, and false otherwise.
For example:
x != yevaluates to true ifxis not equal toy.a != 10evaluates to true if the value of variableais not equal to 10.
Here's an example in C:
#include <stdio.h>
int main() {
int x = 5;
int y = 10;
if (x != y) {
printf("x is not equal to y\n");
} else {
printf("x is equal to y\n");
}
return 0;
}
In this example, since x is not equal to y, the condition x != y evaluates to true, and the message "x is not equal to y" will be printed.
