NettetThe output will be 4. Here is how the logic works on your case: Given : a = 3 b = 2 Then : b = a++ which means take a value to b and then increment the a value. so b value is same as a (before the increment), so with that statement, their value become: b = 3 (same as a before increment) a = 4 (the value change because we got increment) Then evaluate … Nettet18. sep. 2013 · This is a bad programming style. int a = 2; int b = a++ + a++; //right to left value of first a++=2 and then a=3 so second a++=3 after that a=4 b=3+2; b=5; int a = 2; … Nettet23. apr. 2015 · $\int_a^{b} f(x) dx$ exists then so does $\int_{a+c}^{b+c} f(x-c)dx$ and these two integrals are equal.

NettetInteger (computer science) In computer science, an integer is a datum of integral data type, a data type that represents some range of mathematical integers. Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in a computer as a group of binary digits (bits).
