loop can be float or character
#include <stdio.h>
int main()
{
for(float i=1.0;i<=5.0;i++){
printf("%f\n", i);
}
for(char ch='a';ch<='z';ch++)

}
return 0;
}

send this code to your coder girl😂😂

#include <stdio.h>
int main()
{
for(int i=1; ;i++){

\\in this code we initialized value but we didn't update so it will be keep printing output continue

printf("I love you <3 ", i);
}
return 0;
}

while statement is little bit different from for statement.

#include <stdio.h>
int main()
{ int i=1;
while(i<=5){
printf("I love you <3 ", i);
i++;
}

return 0;
}

while loop

#include <stdio.h>
int main()
{ int n;
printf("Enter n : ");
scanf("%d", &n);
int i=1;
while (i<=n){
printf("%d\n", i,n);
i++;
}
return 0;
}

do-while loop

#include <stdio.h>
int main()
{
int i=1;

do
{
printf("%d\n", i);
i++;
} while (i<=5);


return 0;
}

Question for you
Print the number from 0 to n, n is given by user.

Question 2 for you
Print the number from n to 0, n is given by user.

C program to print the sum of FIrst n Natural Numbers.

#include <stdio.h>
int main() {
int n;
printf("enter number : ");
scanf("%d", &n);

int sum = 0;
for(int i=1; i<=n; i++){
sum = sum + i;
}
printf("sum is %d \n", sum);
return 0;
}

"C" program that reads a character and prints out whether or not
it is a vowel or a consonant.


#include <stdio.h>
int main(){

char ch;

printf("Enter letter : ");
scanf("%c", &ch);

if(ch =='a' ch =='e' ch =='i' ch =='o' ch =='u'
ch =='A' ch =='E' ch =='I' ch =='O'|| ch =='U'){
printf("%c is a Vowel\n", ch);
}

else {
printf("%c is a Consonent" ,ch);
}

return 0;
}
