Armstrong Number Program in C++, C Plus Plus CPP with Flowchart.

An Armstrong number of three digits is an integer in such a way that the sum of the cubes of all its digits is equal to the number itself.

## Example of Armstrong number

371 is an Armstrong number since (3*3*3 =27)+ (7*7*7=343) + (1*1*1=1) =(27+343+1)=  371.
Armstrong number 1: 0
Armstrong number 2: 1
Armstrong number 3: 153 since (1*1*1=1) + (5*5*5=125) + (3*3*3=27)= (1+125+27)
Armstrong number 4: 370
Armstrong number 5: 371
Armstrong number 6: 407
