Hi ! I am here putting simple C program to demonstrate Loops and array in C language. Code is only for my C programmer friends,not for my C++ reader please wait for my next post regarding C++. This post is just because it urgently required by my C programmer friends.
Problem Definition: Program to count the number of student who has pass in a particular subject in a given class and count Passing percentage
void main()
{
/* Variable Declaration */
int student[100];
{
/* Variable Declaration */
int student[100];
// Declare integer array assuming max students are 100
int nCount=0,i=0,passCounter=0;
float passPercentage=0;
clrscr();
printf("\nEnter Number of Students: "); // Printing Message
scanf("%d",&nCount); // Get count of number of students
//Save marks for each student
printf("\nEnter marks of student in sequence\n");
for(i=0;i<nCount;i++)
{
printf("\nEnter mark for student number %d :",i+1);
int nCount=0,i=0,passCounter=0;
float passPercentage=0;
clrscr();
printf("\nEnter Number of Students: "); // Printing Message
scanf("%d",&nCount); // Get count of number of students
//Save marks for each student
printf("\nEnter marks of student in sequence\n");
for(i=0;i<nCount;i++)
{
printf("\nEnter mark for student number %d :",i+1);
// i+1 because for loop starts from 0
scanf("%d",&student[i]);
scanf("%d",&student[i]);
// Dont write i+1 here because it saves number from 0 in Array
}
// Calculating count of pass students, here criteria of Passing is 40
for(i=0;i<nCount;i++)
{
//checking mark of each student starting
if(student[i]>40)
{
passCounter++; // Incrementing counter of Passing student
}
}
// Calculating Percentage of Passing student
passPercentage=(passCounter/nCount)*100;
//Displaying result
printf("\nCount of Pass Students are %d",passCounter);
printf("\nPercentage of Pass students are%f",passPercentage);
getch();
}
}
// Calculating count of pass students, here criteria of Passing is 40
for(i=0;i<nCount;i++)
{
//checking mark of each student starting
if(student[i]>40)
{
passCounter++; // Incrementing counter of Passing student
}
}
// Calculating Percentage of Passing student
passPercentage=(passCounter/nCount)*100;
//Displaying result
printf("\nCount of Pass Students are %d",passCounter);
printf("\nPercentage of Pass students are%f",passPercentage);
getch();
}
Comment me for any query regarding program.
