Here you will get codes of DSUS (DSA) and all basic to advanced code of C language
#notice:
Do not copy paste these codes try to understand the concept of the code.
#If you have any query or doubt in c programming you can ask me directly.

Thanks to all for joining the group...
Happy coding :)

1. First C program :-

#include <stdio.h>

int main() {
printf ("Hello World!");
return 0;
}

2. C program to add two integers:-
#include <stdio.h>

int main() {
int a = 5, b = 4;
printf ("sum = %d",(a+b));
return 0;
}

3. C program to subtraction of two integers:-
#include <stdio.h>

int main() {
int a = 5, b = 4;
int c;
c = a-b;
printf ("subtraction = %d",c);
return 0;
}

4. C program to add and subtract two integers on user based input:-
#include <stdio.h>

int main() {
int a,b;
int sum =0, sub = 0;
printf("enter two numbers: \n");
scanf("%d %d",&a,&b);
sum = a+b;
sub = a-b;
printf("sum = %d\nsub = %d", sum, sub);
return 0;
}

5. Program to print n natural numbers:-
#include <stdio.h>
int main() {
printf ("***NATURAL NUMBERS***\n");
int a,b;
printf("Enter a number:\n");
scanf("%d\n",&a);
printf ("Enter second number:\n");
scanf ("%d\n",&b);
for(int i=a;i<=b;i++){
printf ("%d\n",i);
}

return 0;
}

6. C program to check whether a number is Armstrong number or not:-
#include <stdio.h>
// armstrong number in c
int main() {
int rem, num, sum=0, temp;
printf ("Enter a number: ");
scanf("%d", &num);
temp = num;

while(num > 0){
rem = num % 10;
sum += (rem*rem*rem);
num /= 10;
}

if(temp == sum){
printf ("Armstrong number!");
}
else {
printf ("Not a armstrong number!");
}
return 0;
}
