請問有無識C programming 嘅朋友仔可以解答我下面呢條題目呀:
就係有一個陣列(array)
係咁嘅{4, 3, 2.5, 4, -2, -4, 10, 8, -1, -3}代表著一間公司嘅利潤
呢家我要寫一條程式, 就係剩係計連續有利潤嘅時段, 但係去到有負數嘅就要停, 到有正數嘅又由頭開始計過, 最後將利潤最高時段嘅結果show出來,
即係話最後結果會係18.0
我試過好多次都係可以跳過啲負數, 但係唔可以將負數隔開嘅正數時段分開來計, 請問有無好心嘅高手們可以幫一幫忙呀?

This should work.

variable int num is the number of elements in the array. If you change the array, change this variable to reflect the correct number of elements in your array.

Yes, there is a * before index. index is a pointer. It will be needed in the sum subroutine and the value of (*index) will be changed if needed.

1. simply change all the double declaration to float.
2. instead of using index as a parameter to the function, use a global variable
3. shoot me an e-mail if there is any more information given/needed

唔好意思, 睇得唔係太清楚, 請問index係唔係前面有個*, 即係pointer符號呀. 唔該:)
