Define a class to accept values into 4x4 array and find and display the sum of each row.
Example:
A[][]={{1,2,3,4},{5,6,7,8},{1,3,5,7},{2,5,3,1}}
Output:
sum of row 1 = 10 (1+2+3+4) sum of row 2 = 26 (5+6+7+8) sum of row 3 = 16 (1+3+5+7) sum of row 4 = 11 (2+5+3+1)The statement used to find the total number of Strings present in the string array String s[] is:
- s.length
- s.length()
- length(s)
