An algorithm is a finite set of steps defining the solution of a particular problem. An algorithm is expressed in pseudo code – something resembling C language or Pascal, but with some statements in English rather than within the programming language
- A sequential solution of any program that written in human language, called algorithm.
- Algorithm is first step of the solution process, after the analysis of problem, programmers write the algorithm of that problem.
Pseudo code
- Input Num
- Initialize Len to zero and Y to Num
- While Y is not zero
- Save Remainder by Y Mod 16 in array HEXD at index Len
- Initialize Y to Y divided 16
- Increment Len
- for(Initialize I to Len-1 ; Condition I Greater than -1 ; Decrement I )
- If HEXD[I] Less than 10
- HEXC[I]=HEXD[I]+48
- Else
- HEXC[I]=HEXD[I]+55
- Initialize HEXC[I] to NULL
- Print HEXC
Detailed Algorithm:
Step 1: Input NUM
Step 2: LEN = 0 & Y=NUM
Step 3: While (Y > 0)
HEXD[LEN]=Y%16
Y=Y/16
LEN++
Step 4: for(I=LEN-1;I>-1;I–)
IF(HEXD[I]<10)
HEXC[I]=HEXD[I]+48;
ELSE
HEXC[I]=HEXD[I]+55;
Step 5: HEXC[I]=NULL
Step 5: Print HEXC
