1. write an lmc (little man computer) program to do the following task. if (value == 0) { some_statements; } next_statement;
2. write an lmc program to add three numbers. the numbers are provided in the in-basket. the sum of the numbers should appear in the out-basket.

The program is given below with appropriate comments for better understanding

Explanation:

1) LMC Program:

LDA A //Load A

SUB B //Subtract from A, B which is 0.

SKZ // skip next statement if A-B == 0 , which is A == 0 as B is zero.

JMP ENDIF // jump to ENDIF point if A not equal to 0, else this step is skipped.

OUT // some statement , not called if A != 0.

ENDIF LDA A // jump statement arrives here if A != 0.

HLT //HALT

2) LMC Program:

//input first number  

INP

//store it at address 99

STA 99

//input second number

INP

//add it to value at 99

ADD 99

//store the resulting sum to 99

STA 99

//input third number

INP

//add the number to value at 99 address(which is the sum of first and second number)

ADD 99

//output sum

OUT

//halt

HLT
