Question 1:
Write a program that initializes the 10 student scores in an array to be zero. It will ask the user to input the scores available. Note that this array of size 10 could be filled up in full or partially. A menu will be displayed afterwards, allowing the user to choose to perform one of the following functions:
1. Count the number of non-zero elements (which means the actual size of the array);
2. Find the maximum and minimum scores in the array through its reference parameters;
3. Find the minimum element among the first n elements (you should ask the user to specify the value for n first, and n should be less than or equal to the actual size of the array);
4. Find the second largest score in the array;
5. Check whether a particular score is found within the f ..

can you at least post your program codes of two questions before asking for help

這個應該是學校的程式作業吧
同唐老鴨說的，總不能重頭到尾全寫出來吧
雖然作業交差，可是自己學到的少之又少呢

同感+1....
程式就是要自己寫過才會有經驗...
剛開始一定都會很辛苦的....
像我們每次拿到作業...
就開始要構思到底要怎麼寫...
那是一個很痛苦的過程...
雖然有時候根本寫不出來...
或是寫完以後連compile都不能過....
但是老師總是說...
就算寫不出來...交個屍體也好...
這樣他才知道哪邊我們不會....

而且...當每完成一個程式的時候...
那種高興的感覺是無法形容的...
所以建議樓主還是先寫出一些...
再PO上來跟大家討論吧~
