finding the highest score .. write a program that prompts the user to enter the number of students and each student's name and score,and finally displays the student with the highest score...


finding number divisible by 5 and 6..write a program that displays all the numbers from 100 to 1000,ten per line,that divisible by5 and 6..


use nested loops to print the following pattern:
6 5 4 3 2 1
5 4 3 2 1
4 3 2 1
3 2 1
2 1
1



write a for loop to compute the sum of
1^3+2^3+3^3+4^3+...+5^3+n^3..

write a program the reads string from the user then count the number of 't' characters and 'p' in a givenstring. enter yes" if you want to continue reading a string.. otherwise enter NO ..



conversion from kilogram to pounds write a program that displays the following two tables side-by-side(note that 1 kilogram is 2.2 pounds)

kilograms pounds pounds kilograms
9.09 20 2.2 1
11.63 25 6.6 3
....
231.82 510 433.4 197
234.09 515 437.8 199
NOTE:
use the following menu for conversion
1:for conversion from kg to pounds
2:for conversion from pounds to kg
3:to exit from the program execution
