3. write a program in C that calculates student grades based on marks given using if else statements.

Objective:
The objective of this program is to calculate student grades based on the marks provided as input using if else statements in the C programming language. By utilizing conditional statements, we can determine the grade corresponding to the marks obtained by the student and provide meaningful feedback on their performance.
Agenda:
The agenda of this program is to guide the user through the process of developing a C program that can analyse student marks and assign grades accordingly. By explaining the logic behind if else statements and their role in decision-making, the user will gain a comprehensive understanding of how to implement this functionality in their own programs.
Purpose:
The purpose of creating a program to calculate student grades based on marks using if else statements is to demonstrate the application of conditional logic in educational assessment. By employing if else statements, we can evaluate student performance objectively and assign grades that reflect their level of achievement. This program serves as a practical example of how to implement decision-making logic in C programming, showcasing the importance of feedback and evaluation in the educational context.
Real-Life Applications:
In real-life scenarios, the concept of calculating student grades based on marks is a fundamental aspect of the education system. Teachers and educators use grading systems to assess student performance, provide feedback, and track academic progress. By automating the process of assigning grades using a program like the one described, educational institutions can streamline the assessment process and ensure consistency in grading practices. Additionally, this program can be adapted for use in online learning platforms, where automated grading systems play a crucial role in providing timely feedback to students.

/* a program in C that calculates student grades based on marks given using if else statements */
#include <stdio.h>
int main()
{
int marks;
printf("Enter the marks:\n ");
scanf("%d",&marks);
if (marks >= 90) {
printf("The is Grade: A\n");
} else if (marks >= 80) {
printf("The is Grade: B\n");
} else if (marks >= 70) {
printf("The is Grade: C\n");
} else if (marks >= 60) {
printf("The is Grade: D\n");
}

printf("The is Grade: F\n");
}
return 0;
}

a program in C programming language that calculates student grades based on marks given using if else statements.

Output:
Enter the marks:90
The is Grade: A

Explanation
Include the #include<stdio.h> Standard Input-Output Library header file to ensures that the functions for input and output processes are accessible.
int main() function definition starts the execution of the program.
The program begins by asking the user to input or enter the student's marks.
It then reads the input label marks using scanf() function and stores them in variables labelled marks.
The program uses a series of if else statements to determine the grade based on the morks scores entered.
The program will display an A GRADE if the marks scored is 90 or higher.
If the marks awarded are between 80 to 89 then B GRADE will be shown and so on.
If the marks count is less than 60 the program shows Grade F for failure.
Finally, the program returns 0 to indicate successful completion of program.
Finally, the program returns 0 to specify successful execution of the program.
