To determine the output of the given code, let's go through each line:
int i=012;
In C, a number starting with a leading 0 is considered an octal (base 8) number. Therefore, 012 is interpreted as the octal value 12, which is equivalent to the decimal value 10.
int j=046;
Similarly, 046 is an octal number. In this case, it is equivalent to the decimal value 38.
int k=056;
Once again, 056 is an octal number, which is equal to the decimal value 46.
printf("i=%d",i);
This line uses the printf function to print the value of i as a decimal number. Since i is 10, the output will be "i=10".
printf("j=%d",j);
Similarly, this line prints the value of j as a decimal number. Since j is 38, the output will be "j=38".
printf("k=%d",k);
Again, this line prints the value of k as a decimal number. Since k is 46, the output will be "k=46".
Therefore, the correct answer is C) 103846.
