How to take input string in assembly language

Unlike in high level languages where arrays can have many dimensions and are accessed by indices, arrays in x86 assembly language are simply a number of cells located contiguously in memory. An array can be declared by just listing the values, as in the first example below. An assembly language (or assembler language) is a low-level programming language for a computer or other programmable device in which there is a very strong (generally one-to-one) correspondence between the language and the architecture's machine code instructions.

Write a subroutine “INSTR” to input a string from the user and save the string in a buffer pointed to by index register X. The input string is terminated by the user with a carriage return character, but is to be terminated in memory with an EOT character. Also write a test program to verify proper operation of the INSTR subroutine. Is a string that tells the compiler how the value will be used in the assembly string, including: For output operands, whether it is only written to, or both read from and written to. Also whether it can be allocated to the same register as an input operand. See 10.4.1 Constraint modifiers. Since the language itself is so limited, most good assembly programs have a lot of macro wizardry involved. ithkuil on Mar 19, 2014 you can use the intel syntax with gas too (see -masm=intel or .intel_syntax noprefix).

using System; class Program { static void Main() { Test("Dot Net Perls"); Test("dot net perls"); } static void Test(string input) { Console.Write("--- "); Console.Write(input); Console.WriteLine(" ---"); // // See if the string contains 'Net' // bool contains = input. Unlike low-level assembly languages, high-level languages have few, if any, language elements that translate directly into a machine's native opcodes. Other features, such as string handling routines, object-oriented language features, and file input/output, may also be present.
