Hey Susie,
The ## is a concatenation operator,
When you pass the two arguments they get concatenated as
i/p --> f(g,g2) g##g2
o/p --> gg2
hence
f(var,12) will give us var12
effectively the printf statement gets modified as
printf("%d",f(var,12)); --> printf("%d",var12);
hence the output is 100 ie the value of var12.

I need your help, i need a Turbo C code for this problem.. hope u'll help me guys.? Your program will have a 3x3 array. The user will input the sum of each row and each column.

Your program will supply the remaining six (6) values and determine the exact location of each value in the array. Example: Input: Sum of row 1: 6 Sum of row 2: 15 Sum of row 3: 24 Sum of column 1: 12 Sum of column 2: 15 Sum of column 3: 18 Value 1: 3 Value 2: 5 Value 3: 6 Output: Sum of Row 1 2 3 6 4 5 6 15 7 8 9 24 Sum of Column 12 15 18 Note: Your program will not necessary sort the walues in the array Thanks..
