The instruction
MOV M, r
in 8085 -
Which of the following characters is allowed in variable names in C?
-
The standard FORTRAN exponential form of decimal number - 0.000000023 is
-
Consider the following program for 8085
If initial contents of register D is decimal number 20, the final content of register D is
MOV A, D
RAL
MOV D, A -
Assertion (A): In C a variable name can have upto 8 characters and special symbols can also be part of variable name.
Reason (R): In C a type declaration at the beginning of program indicates the type of variable name used in the program.
-
A string constant in basic is
-
Assertion (A): In 8085 when RESET OUT goes low processing begins.
Reason (R): CPU remains reset till RESET IN signal goes high.
