Relational Operators Relational operators are used to compare two values and return a boolean result (true or false). These operators compare the values based on the relationship between them. Here are the most common relational operators: ==: Equality operator. Returns true if both operands are equal. a == b // returns true if a equals … Read more
In programming, assignment operators are used to assign values to variables. Basic and compound assignment operators are two types of these operators. Basic Assignment Operator (=) The basic assignment operator is represented by the single equal sign (=). It assigns the value of the expression on its right-hand side to the variable on the left-hand … Read more
Output of the program: #include <stdio.h> void main(void) { int b; float a, c, d, e, f; a = 14.84; b = 7; c = a – b; printf(“\nc=%f”, c); // c = 14.84 – 7 = 7.840000 d = a / b; printf(“\nd=%f”, d); // d = 14.84 / 7 = 2.120000 e = … Read more

7 + 5(3 + 4) → 7 + 5 * (3 + 4) → 7 + 5 * 7 → 7 + 35 = 42 100 / 10 / 4 → 10 / 4 → 2 (integer division) 50 % 13 % 3 → 50 % 13 = 11, then 11 % 3 = 2 … Read more
printf() is used to display output to the screen, whereas scanf() is used to take input from the user. printf() formats and outputs data, while scanf() reads and stores data from the user into variables.Example: int num; scanf(“%d”, &num); // User input is stored in ‘num’ printf(“You entered: %d”, num); // Output the value of … Read more
The printf() function is used to print formatted output to the console. It allows us to display data in a specified format. For example, to print an integer and a floating-point number: int a = 5; float b = 3.14; printf(“a = %d, b = %f”, a, b); This will print “a = 5, b … Read more
