Variables A “variable” is a place where we keep a value. A = 10 ; // The value 10 is stored in A. Any statement after the sign “//” is NOT part of the program. It is a comment made by the programmer. WSalary = 800 ; // Any statement can go here. A semicolon is required at the end of each C variable in the program needs to be declared in the beginning of the program. | Programming Concepts (Part A) ENGR 10 Introduction to Engineering What is a program? WHITE CAKE RECIPE Preheat oven to 350 degrees F (175 degrees C). Grease and flour a 9x9 inch pan. In a medium bowl, cream together the sugar and butter. Beat in the eggs. Stir in the vanilla. Combine flour and baking powder, add to the creamed mixture and mix well. Stir in the milk until batter is smooth. Pour or spoon batter into the prepared pan. Bake for 30 to 40 minutes in the preheated oven. A computer program is an ordered list of instructions. It’s like a recipe! In Summary A math example y = [ 3 × ( a × a + 7) ] / b + 4 a2 a2 + 7 3 × (a2 + 7) = 3a2 + 21 (3a2 + 21) / b (3a2 + 21) / b + 4 Sequential Solving following Math conventions for correct answer. Consider the sequential execution of the above expressions to find the value of y: p = a x a; q = p + 7; r = 3 x q; s = r / b; y = s + 4; y = [ 3 × ( a × a + 7) ] / b + 4 An Empty EasyC program C program Flow chart Your program goes here.
