The main differences between a JMP instruction and a CALL instruction is as follows –If a JMP instruction is executed, we jump to the destination location, and the execution carries on from there, without bothering to come back later to the instruction after the JMP. On the other hand, if a CALL instruction is executed, we jump to the subroutine, and the execution carries on from there till the RET instruction is executed in the subroutine, and then we come back to the instruction after the CALL in the main program.The address of the next instruction after the CALL instruction ...

Here is a C++ Program to Perform Greedy ColoringAlgorithm:Begin    Take the number of vertices and edges as input.    Create function greedyColoring() to assign color to vertices:    A) Assign the first color to first vertex.    B) Initialize the remaining vertices.    C) Declare a temporary array to store the available colors.    D) Assign color to the remaining vertices.    Print the solution. EndExample Code#include #include using namespace std; int n,e,i,j; vector g; vector col; bool visit[1001]; void greedyColoring() {    col[0] = 0;    for (i=1;i

We use Timing and Controlling unit in 8085 for the generation of timing signals and the signals to control. All the operations and functions both interior and exterior of a microprocessor are controlled by this unit. X2 and CLK output pins: To do or rather perform the operations of timing in the microcomputer system, we have a generator called clock generator in the CU of 8085. Other than the quartz crystal the complete circuit of the oscillator is within the chip. The two pins namely X1 and X2 are taken out from the chip to give the connection to the ... Read More

What is difference between int and const int& in C/C++?

Here we will see what are the differences between int and const_int& in C or C++.The int is basically the type of integer type data. And const is used to make something constant. If there is int& constant, then it indicates that this will hold the reference of some int type data. This reference value is constant itself. So the const is redundant. The compiler may return warning or some error.The const int& is same as int const&. So this refers to a constant integer. The integer cannot be modified through the reference.

Temporary register is also an 8-bit register which the programmer can’t access at all. It is temporarily stored inside 8085 microprocessor which is 8 bit operand to the instruction set. For example, when the fetching of instructions “MVI M, 34H” is done the instruction register IR register will receive the opcode for MVI M, and the Temp register receives 34H.The operations of arithmetic and logical sequence carried out involves two operands, among which one is operand is provided by the accumulator, and the other operand is provided by the Temp register. For example, in the addition process the instruction to ... Read More
