Format specifiers in C are special placeholders used in input and output functions, such as printf and scanf, to indicate the data type of the variable being processed. They begin with a percent sign (%) followed by a character that specifies the type, such as %d for integers, %f for floating-point numbers, and %s for strings. To use them, you include the format specifier in the format string of the function alongside the corresponding variable as an argument. For example, printf("Value: %d", myInt); will print the integer value stored in myInt.

A full adder can be implemented using a 3-to-8 decoder by using the sum and carry outputs of the adder as the decoder's outputs. Connect the three inputs (A, B, and Cin) to the decoder, which will activate one of its eight outputs based on the binary combination of these inputs. The sum output can be obtained by combining the appropriate activated outputs with XOR gates, while the carry output can be derived using OR gates to combine specific activated outputs. This setup allows the decoder to effectively represent the logic required for a full adder.

Instruction Level Parallelism (ILP) can be implemented through techniques such as pipelining, superscalar architecture, and out-of-order execution. Pipelining allows multiple instruction stages to be processed simultaneously, while superscalar architectures enable multiple instruction executions per clock cycle.
