In the first if condition the f==d is set to be true
So, both of them are equal will be printed.

Only recursion feeds value to it again and again in other loops we have to write code to iterative values with i++ or i= i-2 etc.

Print a*b/c-d
Print a*b/(c-d)
Here the precedence will be followed in the 1st case the The value will be 20*10 =200/20=10 then 10-10=0
In a*b/(c-d) the value will be 200/10 = 20
Hence the answer is (the output will have difference of 20)

User Explanation

Once you attempt the question then PrepInsta explanation will be displayed.

Explanation:

Step 1: int a = 300, b, c; here variable a is initialized to \'300\', variable b and c are declared, but not initialized.
Step 2: if(a >= 400) means if(300 >= 400). Hence this condition will be failed.
Step 3: c = 200; here variable c is initialized to \'200\'.
Step 4: printf(\"%d, %d, %d\\n\", a, b, c); It prints \"300, garbage value, 200\". because variable b is not initialized.

User Explanation

Once you attempt the question then PrepInsta explanation will be displayed.

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
