Table of Content Decision control Statement if-else statement if statement Nesting of if-else Dangling else problem else-if ladder If-else statement C uses the keyword if and else to implement the decision control statement. The general form of this statement look like this: Syntax:                       if(expression)                      statement1;                 else                      statement2; The expression inside the parenthesis is evaluated and  if it is true(Non-zero value), then state...

 Control statements in C Control statements are executed sequentially in the order in which they appear in the program. But sometimes we may want to use a condition for executing only a part of program. Also many Situation arise where we may want to execute some statements several times. In other word , the control instruction determine the ' flow of control ' in  a program. There are different types of Control statement in C Language : Sequence Control statement  The Sequence Control statement ensures that the instructions are executed in the same order in which they appear in the program.  A group of statements enclosed within a pair of curly braces {}. The statements inside a block are executed Sequentially.  The general form is : statement1 statement2 ................. ................. For example : l = 4 ;  b = 2; area = l*b; printf("Area=%d", area); In the above example first declare the value of l and b after that find area = l*b then print. ...

 Practice program 1. Write a  program that enters temperature in Celsius and converts that into Fahrenheit. solution : first you can write program in your IDE create a logic how to solve the problem  ※  convert temperature  Celsius  to Fahrenheit use  😊 Formula : ℉=( ℃ × 1.8) + 32 OR ℉=( ℃ × 9/5) +32 #include <stdio.h> int main() {     /*program to convert temperature Celsius to Fahrenheit*/     float C, F;     printf( "Input the Temperature in degree Celsius:" );     scanf( "%f" , &C);     F = (C * 9 / 5 ) + 32 ;     printf( "%.2f degree Celsius = %.2f degree Fahrenheit" , C, F);     return 0 ; } Output: Input the Temperature in degree Celsius:31.5 31.50 degree Celsius = 88.70 degree Fahrenheit 2. Write a program to accepts the radius of a circle and calculates the area and perimeter of that circle. solution : logic of that program : ※ accept the value of ra...
