Assignment 3
• In this assignment, you have to implement Arithmetic Operations for a very large number (Even larger than long long int).
• Basic operations which are needed to be implemented are: Addition, Subtraction, Multiplication and Division.
• Other operations includes: square root, Absolute value and power.
• Programming languages allowed are ANSI-C and C++.
• You are only allowed to use stdio, string and other libraries which inherently doesn’t implement big number library.
• Your submission should contain a zipped folder whose name is your entry number and should contain the folder having all the .c /.cpp files and a makefile.
§ e.g. Your submission will have a zip folder(2018MCS2018.zip) which contains another folder(2018MCS2018) having all codes and makefile
• Your main executable should be named as mainfile which is made by make command.
• mainfile should take two command line arguments i.e. <Name of Input file and <Name of
Output file
§ Your code should run like: ./mainfile input.txt output.txt
• Input.txt (i.e. the input file) will contain the different queries, corresponding to each arithmetic operations.
• Query Format: Each line of input file corresponds to a query which is in the format:
§ <Operator<SPACE <Operand 1<SPACE <Operand 2 if required Operator can be one of the strings: ADD, SUB, MUL, DIV, SQRT, ABS, POW Operand will be String representing a floating point decimal number.
• For each query, you have to print a single lined output in Output.txt which is also a string corresponding to floating point decimal number.
• You need to handle the cases where the operand or results are negative values.
• Please refer to sample input files with corresponding output files for further details.
• For floating point results the precision should be correct up to 20 digits after decimal point.
