b)  
c)  
What is the need of precedence and associativity of operators in C? (1 M)  
Summarize bitwise operators, logical operators and assignment operators as  
per precedence and associativity with respect to each other. (for each  
operator 1 M)  
If a four-digit number is input through the keyboard, write a program to  
calculate the sum of its digits without using control flow statements. (2 M)  
calculate the amount of memory required to data types while program is  
executing on machine. Maximum amount memory =12 Byte (2 M)  
otherwise (1 M).  
Program: (Add header files and main function)  
int num, a, n;  
int sum = 0;  
printf("\n Enter a 4 digit number:")  
scanf("%d", &num);  
a = num % 10;  
n = num/10;  
sum = sum + a;  
a = num % 10;  
n = num/10;

sum = sum + a;  
a = num % 10;  
n = num/10;  
sum = sum + a;  
a = num % 10;  
n = num/10;  
sum = sum + a;  
printf(“\n The sum of the 5 digit of %d is %d",num, sum);
