Solve the following:
Question is based on logical operators and relations operators

#include<stdio.h>
int  main()
{
	int a=10,b=20,c;
	/* 1. */
	c=a>=10 && b>=a;
	printf("1. %d\n",c);
	/* 2. */
	c=a<=10 && b>=a;
	printf("2. %d\n",c);
	/* 3. */
	c=a>=6 && b<=a;
	printf("3. %d\n",c);
	/* 4. */
	c=!(a>=130 && b>=a);
	printf("4. %d\n",c);
	/* 5. */
	c=a>=10 && !(b>=a);
	printf("5. %d\n",c);
  
   return(0);
}

/* Output */
