C Program to Find Factorial of a Number!

Posted on May 4, 2017 by agurchand

Here is another interesting program for school students who are interested in learning C programming. This program will calculate the factorials and print all the values as a factorial pyramid. Example (C Program to find factorial of a number):

#include <stdio.h>
int main()
{
	int num, fact = 1, i;
		
	//print about the program
	printf("C Program to calculate factorial..\n");
    printf("Enter Number to calculate factorial: ");
   	
	//get the input value from the user
	scanf("%d", &num);
		
	//loop till the iterator $i equals to $number
	for (i = 1; i <= num; i++){
		
		//formula to calculate factorial is to 
		//multiply the iterator i value with fact value.			
		fact = fact * i;
		
		//print fact to show the factorial pyramid
		//or put this line out of this 'for loop' to show only the total value
		printf("%d\n", fact);
	}
    return 0;

C Program – Convert string from Uppercase to Lowercase!

Posted on May 4, 2017 by agurchand

Let’s write an useful C program today. This C Program will convert any Uppercase string to Lowercase. For this, we are going to use tolower() function which is already available in C itself.

#include <stdio.h>

int main() {

	char mystr[100];
	int i=0;
		
	//print about the program
	printf("C Program to convert uppercase to lowercase\n");
    printf("Enter your full name in CAPS: ");
   	
   	//get the input string from user
   	fgets(mystr, 100, stdin);
   	
   	//loop through the string and convert into lower letters
    while( mystr[i] ) {
      //store back the lower letter to mystr
      mystr[i] = tolower(mystr[i]);
      i++;
   }    
   
   //print the lower letters
   printf("Lowercase: %s", mystr);
}

fgets(mystr, 100, stdin);

//loop through the string and convert into lower letters

while( mystr[i] ) {

mystr[i] = tolower(mystr[i]);

}
