Write a program that adds together pairs of numbers and prints their sums.
Each line of the input file contains two integers (a and b) separated by spaces.
For each line of input there should be a corresponding line of output saying a+b=c where a and b are replaced by the inputs, and c is replaced by their sum. There should be no spaces or leading zeros.
The inputs will be integers between 0 and 2,000,000,000 inclusive.
BEWARE: This problem is not quite as simple as it may seem. Think carefully about what the input limits really imply. The real problems do not give you warnings like this.
1 2 123 123 999 9
1+2=3 123+123=246 999+9=1008
