Algorithm:
Step 1 Start the process
Step 2 Prompt the user with converter choice 1. Currency 2.Distance 3. Time 4. Exit and the
choice.
Step 3 If user selects a Currency Converter then proceed to step 4
Step 4 Proceed with prompting Currency Converter Choices
1.DOLLER to INR 2. EURO to INR 3. YEN to INR
4.INR to DOLLER 5. INR to EURO 6. INR to YEN
7.Exit and get the user choice.
Step 4.1 If option 1 selected get in DOLLER and display DOLLER * 66.89 as INR
Step 4.2 If option 2 selected get in EURO and display EURO * 80 as INR
Step 4.3 If option 3 selected get in YEN and display YEN * 0.61 as INR
Step 4.4 If option 4 selected get in INR and display INR / 66.89 as DOLLER
Step 4.5 If option 5 selected get in INR and display INR / 80 as EURO
Step 4.6 If option 6 selected get in INR and display INR / 0.61 as YEN
Step 4.7 If option 7 selected exit from currency converter choice goto step 2
Step 5 If user selects a Distance Converter then proceed to step 6
Step 6 Proceed with prompting Distance Converter Choices
- METER to KILOMETER 2. MILES to KILOMETER
3. KILOMETER to METER 4. KILOMETER to MILES
5. Exit and get the user choice.
Step 6.1 If option 1 selected get in METER and display METER / 1000 as
KILOMETER
Step 6.2 If option 2 selected get in MILES and display MILES * 1.60934 as
KILOMETER
Step 6.3 If option 3 selected get in KILOMETER and display KILOMETER * 1000 as
METER
Step 6.4 If option 4 selected get in KILOMETER and display KILOMETER / 1.60934
as MILES
Step 6.5 If option 5 selected exit from distance converter choice goto step 2
Step 7 If user selects a Time Converter then proceed to step 8 currency
Step 8 Proceed with prompting Time Converter Choices
- HOURS to MINUTES 2. HOURS to SECONDS
3. MINUTES to HOURS 4. SECONDS to HOURS
5. Exit and get the user choice.
Step 8.1 If option 1 selected get in HOURS and display HOURS * 60 as MINUTES
Step 8.2 If option 2 selected get in HOURS and display HOURS * 3600 as SECONDS
Step 8.3 If option 3 selected get in MINUTES and display MINUTES / 60 as HOURS
Step 8.4 If option 4 selected get in SECONDS and display SECONDS / 3600 as
HOURS.
Step 8.5 If option 5 selected exit from tim converter choice and goto step 2
Step 9 If user selects exit then display Thank You !!! and exit from the system
Step 10 Stop the process
