The C program to display student results demonstrates the working of conditional statement in the C language. The program takes student’s marks in percentage (%) as input , process the input value and displays the results (pass or fail) as output.
The output depends on the conditional statement in the example program.
Learn C programming basics before you begin with this example program.
Problem Definition
The program decides whether a student has passed or failed an exam. If the input is in percentage mark ( say 70%), a simple conditional statement checks if given percentage mark is below 40%.
( mark < 40)
The student result is a pass when mark is above 40% , else the student has failed. The result is displayed at the console.Here we list the steps involved in processing input values.
- Receive input in percentage mark (%)
- Check if the given mark is above below 40%
- If below 40%, then the student has failed
- Else the student passed.
- Display the result.

Program Code – Display Student Results
/*Show result of student using Marks */
#include <stdio.h>
#include <conio.h>
int main()
{
int marks,i;
/* Read student marks */
printf("Enter the marks (in percentage ) of Student:");
scanf("%d",&marks);
/* display result */
if(marks < 40)
{
for(i=0;i<40;i++)
printf("_");printf("\n\n");
printf("Result = Failed\n");
for(i=0;i<40;i++)
printf("_");printf("\n\n");
}
else
{
for(i=0;i<40;i++)
printf("_");printf("\n\n");
printf("Result = Passed\n");
for(i=0;i<40;i++)
printf("_");printf("\n\n");
}
system("pause");
return 0;
}
Output
The student entered his or her mark which is 60%. The given mark are above 40%, required condition to pass the exam. Hence, the student result is passed.
Enter the marks ( in percentage ) of Student:60
