#include <stdio.h>

int main(void)

{

// Initialize variables and note that c is not less than d, which is one of the conditions to test for

// therefore the entire expression should be evaluated as false

int a = 5, b = 6, c = 5, d = 1;

int x;

// Evaluate the expression without parentheses

x = a < b || a < c && c < d;

printf("Given expression:\n");

printf("x = a < b || a < c && c < d\n");

printf("Without parentheses the expression evaluates as %d", x);

// Evaluate the expression with parentheses

x = (a < b || a < c) && (c < d);

printf("\n\nWith parentheses:\n");

printf("x = (a < b || a < c) && (c < d)\n");

printf("With parentheses the expression evaluates as %d\n", x);

return 0;

}

**
Output example:**

Given expression:

x = a < b || a < c && c < d

Without parentheses the expression evaluates as 1

With parentheses:

x = (a < b || a < c) && (c < d)

With parentheses the expression evaluates as 0
