#include < stdio.h > int main() { int a = 20, b = 30, c; if( !(a > b) ) b = 50; c = 70; printf("b = %d and c = %d\n", b, c); return 0; }
In this c source code, a is 20 and b is 30. Inside if condition we check if a is greater than b. But a is less than b, so it returns false(0). But we’ve a Logical NOT operator(!) surrounding the false result. So it converts it to true. Hence the next line of code that is, b = 50 gets executed.
So the output is: b = 50 and c = 70
