Answer: Option C
Solution
Answer: Option C
Solution:
In the given C program code snippet:
void main()
{
int c = - -2;
printf("c=%d", c);
}
The line int c = - -2; is evaluated as follows:
1. The expression `- -2` involves two consecutive negative signs. 2. The first negative sign (`-`) acts as the unary minus operator, and the second negative sign (`-`) is also a unary operator. 3. When two negative signs are used together, they effectively cancel each other out, so `- -2` becomes `2`.
Therefore, the variable `c` is assigned the value `2`.
The output of the `printf` function will be: 2
