Mini Projects in C Programming
Introduction to Mini Projects in C Programming
Mini projects in C programming help you apply all the concepts you have learned, such as arrays, functions, pointers, file handling, and dynamic memory.
Building mini projects in C programming improves practical skills and prepares you for real-world development.
Project 1: Student Record Management System
This project stores and manages student data using structures and file handling.
Features
- Add student record
- Display records
- Save data in file
Code Example
struct Student {
int id;
char name[20];
};
int main() {
FILE *fp;
struct Student s;
fp = fopen(“student.txt”, “a”);
printf(“Enter ID: “);
scanf(“%d”, &s.id);
printf(“Enter Name: “);
scanf(“%s”, s.name);
fprintf(fp, “%d %s\n”, s.id, s.name);
fclose(fp);
printf(“Record saved successfully”);
return 0;
}
Project 2: Simple Calculator
Performs basic arithmetic operations.
Code Example
int main() {
int a, b;
char op;
printf(“Enter operator (+, -, *, /): “);
scanf(” %c”, &op);
printf(“Enter two numbers: “);
scanf(“%d %d”, &a, &b);
switch(op) {
case ‘+’: printf(“Result = %d”, a + b); break;
case ‘-‘: printf(“Result = %d”, a – b); break;
case ‘*’: printf(“Result = %d”, a * b); break;
case ‘/’: printf(“Result = %d”, a / b); break;
default: printf(“Invalid operator”);
}
return 0;
}
Project 3: File Copy Program
Copies data from one file to another.
int main() {
FILE *src, *dest;
char ch;
src = fopen(“source.txt”, “r”);
dest = fopen(“dest.txt”, “w”);
while((ch = fgetc(src)) != EOF) {
fputc(ch, dest);
}
fclose(src);
fclose(dest);
printf(“File copied successfully”);
return 0;
}
Project 4: Dynamic Array Program
Uses dynamic memory allocation.
#include <stdlib.h>
int main() {
int n;
int *arr;
printf(“Enter size: “);
scanf(“%d”, &n);
arr = (int*) malloc(n * sizeof(int));
for(int i = 0; i < n; i++) {
scanf(“%d”, &arr[i]);
}
printf(“Elements:\n”);
for(int i = 0; i < n; i++) {
printf(“%d “, arr[i]);
}
free(arr);
return 0;
}
Project 5: Palindrome Checker
Checks whether a string is palindrome.
#include <string.h>
int main() {
char str[50];
int i, len, flag = 1;
printf(“Enter string: “);
scanf(“%s”, str);
len = strlen(str);
for(i = 0; i < len / 2; i++) {
if(str[i] != str[len – i – 1]) {
flag = 0;
break;
}
}
if(flag)
printf(“Palindrome”);
else
printf(“Not Palindrome”);
return 0;
}
