Loop

1. Write a program for display your name 50 times in C language.
   
   #include <stdio.h>

   int main(){

   for(int i=0; i<50; i++;){

   printf(“Suman Adhikari”);

   }

   
   

   return 0;}

   
   
   
   
   
   
2.  "Write a program that uses a “for” loop to compute and prints the sum of a given numbers of squares."
   
   #include <stdio.h>

   
   

   int main() {

       int n, sum = 0;

   
   

       // Prompt the user for input

       printf("Enter the number of terms: ");

       scanf("%d", &n);

   
   

       // Compute the sum of squares using a for loop

       for(int i = 1; i <= n; i++) {

           sum += i * i;

       }

   
   

       // Print the result

       printf("The sum of the squares of the first %d natural numbers is: %d\n", n, sum);

   
   

       return 0;

   }

   
   
   
   
   
   
3. "Write a program that uses a “while” loop to compute and prints the sum of a given numbers of squares. For example, if 4 is input, then the program will print 30, which is equal to 12+22+32+42.
   
   #include <stdio.h>

   
   

   int main() {

       int n, sum = 0, i = 1;

   
   

       // Input the number of squares

       printf("Enter the number of squares: ");

       scanf("%d", &n);

   
   

       // Compute the sum of squares using a while loop

       while (i <= n) {

           sum += i * i;

           i++;

       }

   
   

       // Print the result

       printf("Sum of squares: %d\n", sum);

   
   

       return 0;

   }

   
   
   
   
   
   
4. Write a program that uses a “while” loop to compute and prints the sum of a given numbers of squares.For example, if 4 is input, then the program will print 30,which is equal to 12+22+32+42."
   
   #include <stdio.h>

   
   

   int main() {

       int n, sum = 0, i = 1;

   
   

       // Input the number

       printf("Enter the number of squares: ");

       scanf("%d", &n);

   
   

       // Compute the sum of squares using a while loop

       while (i <= n) {

           sum += i * i;

           i++;

       }

   
   

       // Print the result

       printf("Sum of squares: %d\n", sum);

   
   

       return 0;

   }

   
   
   
   
   
   
   
5. Write a program to input string and display 20 times.
   
   #include <stdio.h>

   
   

   int main() {

       char str[100];

       int i;

   
   

       // Input the string

       printf("Enter a string: ");

       fgets(str, sizeof(str), stdin);

   
   

       // Display the string 20 times

       for (i = 0; i < 20; i++) {

           printf("%s", str);

       }

   
   

       return 0;

   }
