What will be the output of the following C code if the code is executed on a 32 bit platform?#include <stdio.h> enum sanfoundry { c = 0, d = 10, h = 20, s = 3 } a; int main() { a = c; printf("Size of enum variable = %d bytes", sizeof(a)); return 0; }

• error
• Size of enum variable = 2 bytes
• Size of enum variable = 4 bytes
• Size of enum variable = 8 bytes

#include <stdio.h> union { int x; char y; }p; int main() { p.y = 60; printf("%d\n", sizeof(p)); }

• Compile time error
• sizeof(int) + sizeof(char)
• Depends on the compiler
• sizeof(char)
