Character Array And Functions

Question:1
C program to input for a string, pass it to a function, and display the string.
Sol:

#include<stdio.h>
void show(char n[])
{
	int i=0;
	while(n[i]!='\0')
	{
		printf("%c\n",n[i]);
		i++;
	}
}
int main()
{
	char n[30];
	printf("Enter any string ");
	gets(n);
	show(n);
}

Output:

Enter any string Hello hi
H
e
l
l
o

h
i

Question:2
C program to input for a string, pass it to a function and display the string and its length.
Sol:

#include<stdio.h>
void show(char n[])
{
	int i=0;
	while(n[i]!='\0')
	{
		printf("%c\n",n[i]);
		i++;
	}
	printf("Length of string %d\n",i);
}
int main()
{
	char n[30];
	printf("Enter any string ");
	gets(n);
	show(n);
}

Output:

Enter any string computer world
c
o
m
p
u
t
e
r

w
o
r
l
d
Length of string 14

Question:3
C program to input for a string, pass it to a function and display total alphabets in the string.
Sol:

#include<stdio.h>
void show(char n[])
{
	int i=0,a=0;
	while(n[i]!='\0')
	{
		printf("%c\n",n[i]);
		if((n[i]>='A' && n[i]<='Z') || (n[i]>='a' && n[i]<='z'))
		a++;
		
		i++;
	}
	printf("Length of string %d\n",i);
	printf("Total alphabets in string %d\n",a);
}
int main()
{
	char n[30];
	printf("Enter any string ");
	gets(n);
	show(n);
}

Output:

Enter any string hello234#$#
