Concept explainers
Describe the difference between the if /else if statement and a series of if statements.
“if/else”if statement:
- “if/else” ifis a conditional statement that controls the condition branching.
- It executes the statements after evaluating the conditional expression.
- The “if” statement evaluates the test expression and when it is evaluated as true, the statement inside the body of “if” statement is executed.
- If the test expression is evaluated as false, it moves to the next if/else statement and the process continues till it reaches the finalif/else statement.
- If the test expression is evaluated as false, the statements in the “else” is executed.
Syntax:
//if conditional statement
if(condition)
{
Statement1
}
//if condition statement2
else if(condition)
{
Statement2
}
//else part
else
{
Statement3
}
Series of “if” statement:
A condition statement that controls the condition branching. The “if” statement evaluates the test expression and when it is evaluatedas true, the statement inside the body of “if” statement gets executed.
Syntax:
// if conditional statement1
if(condition)
{
Statement1
}
// if conditional statement2
if(condition)
{
Statement2
}
Explanation of Solution
Difference between if/else if statement and a series of if statement:
if/else if statement | if statement |
The condition gets tested until one conditional block is found to be true. | The conditions get validated for each of the condition cases given in a series. |
The conditions are being evaluated to true to execute the statement. On evaluating true, the statement gets execute and exits the controls. | Each series of condition needs to be evaluated for the execution of series of statement present. The control gets validated for each condition and based the valuation of condition; the control exits the condition. |

The program will accept 3 scores and computes the average score. Determine the grade based on the following rules: - If the average score is equal or greater than 90, the grade is A. - If the average score is greater than or equal to 70 and less than 90, the grade is B. - If the average score is greater than or equal to 50 and less than 70, the grade is C. - If the average score is less than 50, the grade is F.
