Input: num: 34638 Output: num: 34638 Size of a long variable: 8 Input: num = -79349367648374345 Output: Type of num: System.Int64 num: -79349367648374345 Size of a long variable: 8
If we input number beyond the range, it shows error-
Integral constant is too large
num: 34638 Size of a long variable: 8
Type of num: System.Int64 num: -79349367648374345 Size of a long variable: 8 Min value of long: -9223372036854775808 Max value of long: 9223372036854775807
