Question

1. Three variables x, y, and z defined as unsigned char, short, and int types in C Programming. What are the maximum values they can take?

2. Compare the following C programs. After execution of this short programs what will be the value of x if printed in function?

void foo(void); int main(void){             foo();             foo();             foo(); return 0; } void foo() {             int x = 1;             x++;               }

void foo(void); int main(void){             foo();             foo();             foo(); return 0; } void foo() {             static int x = 1;             x++;               }

3 unsigned char:- Maximum value for an unsigned char = 255. We can take .255 as maximum. Short: we can take .32767 as Maximum int: we can take .2147483 647 as Maximum

main.c 1 2 3 #include <stdio.h> int main() À JOVOU A int x; void foo(void); int main(void){ foo(); foo(); foo(); return 0; void foo(); 13 14 static int x=1; x++; 15 16 17 printf("%d",x); 18 } 19

input 32765 ... Program finished with exit code o Press ENTER to exit console.

main.c 1 2 #include <stdio.h> int main() int x; void foo(void); int main(void){ foo(); foo(); foo(); return 0; 10 11 12 void foo(); - - 13- 14 int x=1; X++; 15 16 17 printf("%d",x); 18 } 19

input 32766 ... Program finished with exit code o Press ENTER to exit console.

Both programs are giving same x value in the function. Because in both programs the function void foo(); is executed one time. So in both programs x value printed as 2. first x will equal to 1 and x will incremented by one.

1)

• Unsigned char value is between 0 to 255. Max value is 255.
• Short value is between -32,768 to 32,767. Max value is 32,767
• Int value is between -32,768 to 32,767. Max value is 32,767
