C program to find area of rectangle

In this Program, User will enter the length and width of the rectangle into two variables length and width. Then, Calculating the Area of the rectangle using the formula Area = length × width. After the successful execution the final area of a rectangle is shown on screen.

C Program Examples
C program to find area of triangle
C program to find area of triangle

In this Program, User will enter the three sides of the triangle a, b, c. Then, Calculating the Perimeter of the Triangle. Moreover, calculating the semi perimeter using the formula (a + b + c) / 2 and calculating the Area of a triangle using Heron’s Formula: sqrt(s * (s - a) * (s - b) * (s - c)). After the successful execution of the program the final area of a triangle is shown on screen.

C Program Examples
C program to find largest number among three numbers
C program to find largest number among three numbers

In this program, three numbers are assigned in to the three variables one by one. Then, compare the two selected of them with the use of comparison operator. Repeat the same process for the other two. After the successful execution of the program the final largest number amongst the three are displayed on the screen.

C Program Examples
C program to get length of string
C program to get length of string

In this program, using a for loop, we have iterated over characters of the string from i = 0 to until '\0' (null character) is encountered. In each iteration, the value of i is increased by 1. When the loop ends, the length of the string will be stored in the i variable.

C Program Examples
C program to check number is armstrong
C program to check number is armstrong

In this program, the number of digits of an integer is calculated first and stored in n. And, the pow() function is used to compute the power of individual digits in each iteration of the second for loop.

C Program Examples
C program to generate multiplication table
C program to generate multiplication table

After the successful compilation of the program, In this program, we used two variables num, and i. The variable num is used to store the input integer number and the variable ‘i’ is used to iterate the loop. Product of the number is given by num*i;

C Program Examples
C program quadratic equation
C program quadratic equation

After the successful compilation of the program, this program displays the following output: Enter values for a, b, c of quadratic equation ax2+bx+c are: If user enters 1, 2, 6 then it displays two distinct complex roots exists: -1.00 + i2.24 and -1.00 - i2.24

C Program Examples
