Structure padding in c interview questions
WebJul 10, 2024 · Structural Padding means aligning the data into blocks of fixed size in order to ease the operations of particular Computer Architectures, Cryptographic algorithms accordingly. We pad(add enough bytes) the operational data (which is not necessarily structured) in order to serve the machine. WebQ) How to clear a particular bit in C? Bitwise AND operator (&) use to clear a bit of integral data type. “AND” of two bits is always zero if any one of them is zero. An algorithm to clear the bits Number &= ~ (1<< nth Position) To clear the nth bit, first, you need to invert the string of bits then AND it with the number.

WebMar 20, 2024 · C Programming Interview Questions – For Freshers 1. Why is C called a mid-level programming language? Due to its ability to support both low-level and high-level features, C is considered a middle-level language. It is both an assembly-level language, i.e. a low-level language, and a higher-level language. WebAnswer (1 of 6): Let us consider two simple examples to understand the concept clearly. Example 1: [code]struct A { char c; char ch; }; int main() { printf("%d bytes ...

WebThe below figure shows the pictorial representation of the structure. The structure has two members; i.e., one is of integer type, and the another one is of character type. Since 1 block is equal to 1 byte; therefore, 'a' variable will be allocated 4 blocks of memory while 'b' variable will be allocated 1 block of memory.

See more Output:16 The largest structure member is int (4 bytes), hence the compiler aligned the memory in the form of 4 bytes. See more Output:16 The largest structure member is double (8 bytes), hence the compiler aligned the memory in the form of 8 bytes.
