মনের বাগানে গোলাপ ফুটেছে

মনের বাগানে গোলাপ ফুটেছে

পারভেজ হুসেন তালুকদার

 

মনের বাগানে গোলাপ ফুটেছে রঙ টুকটুকে লাল 

সে ফুল তুলতে হবো বুঝি আমি ষোলোআনা নাজেহাল। 

ফুলের কাঁটারা লাজের বরনে বাঁধা দেবে জানি ঠিক,

মনের মরুতে চোরাবালিগুলো  ফাঁদ এঁটে চিকচিক। 

তবু আমি ফের প্রেমের যাদুতে  মুছে নিবো বাঁধা সব,

মনের বাগানে ফোটা ফুল হবে  প্রেম-পণে কলরব।

int syl_dha_km;

float syl_dha_miles, syl_dha_meters, syl_dha_cms;

syl_dha_km = 245;

syl_dha_miles = syl_dha_km * 0.621371;
syl_dha_meters = syl_dha_km * 1000;
syl_dha_cms = syl_dha_meters * 100;

printf("Sylhet To Dhaka (in KMs): %.3f\n", syl_dha_km);
printf("Sylhet To Dhaka (in Miles): %.3f\n", syl_dha_miles);

return 0;
}

2. Question: Write a program that will take the value of ‘a’ and ‘b’ from the user and calculate the area of an ellipse using the formula: Area = πab (where π = 3.14).

Solution:

#include
int main()
{
float const pi = 3.14;
float a, b, area;
printf("Enter the value of a: ");
scanf("%f", &a);
printf("Enter the value of b: ");
scanf("%f", &b);
area = pi * a * b;

}

3. Question: In a supermarket, the prices of some products are given below:

Apple = Tk. 140/kg

Orange = Tk. 90/kg

Grapes = Tk. 360/kg

ভালোবাসারই দিবস আসবে তবে

ভালোবাসারই দিবস আসবে তবে
পারভেজ হুসেন তালুকদার

মানুষে মানুষে ভালোবাসা হোক গাঢ়
বিবাদ-বিভেদ দীর্ঘ না হোক আরো
অধিকার হেরে কেউ বা না হোক দুখী
পথেঘাটে পড়ে না থাকুক পোড়ামুখী।

যত বাঁধা আর অশুভ হৃদয় চিরে
মানুষে মানুষে সমতা আসুক ফিরে
ধরাতে সকলে সমান যখন হবে
ভালোবাসারই দিবস আসবে তবে।
