Explanation on a program code:
we have a declaration of 3 variables with the int type, that is 3 variables which will save value of an integer number. At once at the declaration x receives value 3. In the second line of the program y and x receive identical value: number 10. In the 3rd line z expression receives result x <10. As x at us it is equal 10, expression 10 <10 will be false, and the result false expression is 0. That is z will receive value 0. The last line we display value of variables through library function of printf. In quotes is a line of a format. Here we specify how to interpret value of variables. \\\\n means word wrapping; x =, y =, z = will be displayed as it is written; %d is a qualifier which specifies that variables which go after a line of a format will be displaid as integer numbers.
The result of a program runtime will be such:
x = 10 y = 10 z = 0
