Programming statements and instructions that are written by the developer. Source code is what a programmer writes, but it is not directly executable by the computer. It must be converted into machine language by compilers, assemblers or interpreters.In some cases, source code can be machine generated by programs that convert the source code of one programming language or dialect into the source code of another language or dialect. See lines of code, compiler, assembler and interpreter.High Level vs. Low LevelMost programmers write in high-level languages such as C/C++ and Java. However, there are programs written in assembly language, which is essentially a mnemonic version of the hardware's machine language. Following are examples of both high and low level for converting Fahrenheit to Celsius.C (High Level) float fahr; printf("Enter Fahrenheit: "); scanf("%f", &fahr); printf("Celsius is %f\n", (fahr-32)*5/9); Python (High Level) printf("Enter Fahrenheit: ") fahr = float(input) cell = ((fahr -32) * 5 / 9, 1) printf("Celsius is {}".format(cell)) Java (High Level) import java.io.*; class Convert { public static void main(String[]args) throws IOException { float fahr; StreamTokenizer in=new StreamTokenizer (new InputStreamReader(System.in)); System.out.print("Enter Fahrenheit "); in.nextToken(); fahr = (float) in.nval; System.out.println ("Celsius is " + (fahr-32)*5/9); } } Intel x86 Assembly Language (Low Level) cseg segment para public 'CODE' assume cs:cseg,ds:cseg start: jmp start1 msgstr db 'Enter Fahrenheit ' crlf db 13,10,'$' nine db 9 five db 5 outstr db 'Centrigrade is $' start1: push ds push cs pop ds mov dx,offset cseg:msgstr mov ah,9 int 21h sloop: cent: call getnumb test ax,ax je exit push ax mov dx,offset cseg:outstr mov ah,9 int 21h pop ax sub ax,32 jns c1 push ax mov dl,'-' mov ah,6 int 21h pop ax neg ax cl: mul five div nine call putval mov dx,offset cseg:crlf mov ah,9 int 21h jmp sloop exit: pop ds mov ah,4ch int 21h getnumb: xor bx,bx llp: mov dl,0ffh mov ah,1 int 21h cmp al,0dh je llr sub al,'0' jb llr cmp al,'9' ja llr xor ah,ah shl bx,1 add ax,bx shl bx,1 shl bx,1 add bx,ax jmp llp llr: mov dx,offset cseg:crlf mov ah,9 int 21h mov ax,bx ret putval: xor bx,bx push bx mov bx,10 llg: xor dx,dx div bx add dx,'0' push dx test ax,ax jne llg bloop: pop dx test dx,dx je endx mov ah,6 int 21h jmp bloop endx: ret cseg ends end start.
