2025: A Year of Exams, Excellence, and Evolution Hi, I am Mayur Gund welcoming you at Mayur's Tech Journey. As the curtains fall on 2025, I look back at a year that was defined by grit, transitions, and the discovery of my true passion. From the silent halls of exam centers to the vibrant development labs of Sanjivani, this year has been an unforgettable journey of growth. The Rigorous Start: The year 2025 began with intense pressure. Every student in India knows the weight of the last week of January—the JEE Mains . My preparation was rigorous, and on 12th February, I received my first boost: a 83 percentile in JEE Mains. While I was still processing this, the HSC Board exams arrived in the same month, requiring a complete shift in focus from entrance logic to descriptive writing. The Frustrating Peak: MHT-CET and Mock A March was perhaps the most challenging month of the year. It was a period of constant mock tests. The frustration of stagnant scores and the repeti...
🔵 Day 3 – My First C Program to Calculate Area of a Circle
Today marks another exciting step in my coding journey. After writing simple introductory programs in Python and C, I finally wrote my first program that solves a real problem in C — calculating the area of a circle.
🧩 The Program {}
#include <stdio.h>
int main()
{
/*
Program : C program to find area of circle
Author : Mayur B Gund
Date : 7 Sep 2025
*/
char r; // character for radius
int b; // integer for radius value
scanf("%c\n", &r); // input for character
scanf("%d", &b); // input for radius value
printf("The area of circle \nwith radius %c = %dcm is \n\t: %f sqcm\n\n",
r, b, 3.14 * b * b);
printf("This program calculates area \nof circle with 100 percent\n accuracy\n");
printf("\tNote: Radius should\n be an integer.");
return 0;
}
📌 Output : 🖥
The area of circle
with radius r = 432cm is {r and 432 are user inputs}
: 585999.360000 sqcm
This program calculates area of circle with 100 percent accuracy
Note: Radius should be an integer.
💡 What I Learned Today
- How to take inputs from the user using scanf.
- Using variables (char + int) together in one program.
- Applying a mathematical formula in C.
- Formatting output clearly with printf.
🚀 Reflection
Compared to my first two programs, this one feels more practical and powerful. It gave me a sense that I’m moving closer to solving real-world problems with code.
- Learning Python 🐍 and C ⚙️ side by side is helping me balance:
- Python → simplicity and fast results.
- C → strong fundamentals and deeper understanding.
Step by step, I’m building a stronger foundation for my programming journey. 🌟
