If we want a search function to search an array for some val

If we want a search function to search an array for some value and return either the index where the value was found, or -1 if not found, which of the following prototypes would be appropriate?

Solution

Say for suppose you want to search an integer value in an integer array

Suitable method prototype:

int search(int[] targetArray,int searchValue);

explanation:

return value:

returns -1 if number not found else return index.

Parameters:

targetArray- Array to be iterated to search

searchValue-value to be searched

Sample implementation:

int search(int[] targetArray,int searchValue)

{

//iterate throught the target array

for (int i=0;i<targetArray.length;i++)

{

if(targetArray[i]==searchValue)//compare value at each index

return i;//if matches return index

}

return -1;//if match is not found in iteration return -1

}
