Question:7
C program to input for a string, pass it to a function, and display total vowels in the string.
Sol:

#include<stdio.h>
void show(char n[])
{
     int i=0,v=0;
     while(n[i]!='\0')
     {
          printf("%c\n",n[i]);
          if(n[i]=='A' || n[i]=='a' || n[i]=='E' || n[i]=='e' || n[i]=='O' || n[i]=='o'
		   || n[i]=='I' || n[i]=='i' || n[i]=='U' || n[i]=='u')
          v++;
          
          i++;
     }
     printf("Length of string %d\n",i);
     printf("Total vowels in string %d\n",v);
}
int main()
{
     char n[30];
     printf("Enter any string ");
     gets(n);
     show(n);
}

/* Output */

Question:8
C program to input for a string, pass it to a function, and display the following.
* Total length of string
* total upper case alphabets
* total lower case alphabets
* total digits
* total spaces
* total special characters
Sol:

#include<stdio.h>
void show(char n[])
{
	int i=0,a=0,ua=0,la=0,d=0,sp=0,spl=0;
	for(i=0;n[i]!='\0';i++)
  {
      printf("%c\n",n[i]);
      if((n[i]>='A' && n[i]<='Z') || (n[i]>='a' && n[i]<='z'))
      {
         a++;
         if(n[i]>='A' && n[i]<='Z')
            ua++;
         else
            la++;
      }
      else
        if(n[i]>='0' && n[i]<='9')
        d++;
      else
        if(n[i]==' ')
            sp++;
        else
            spl++;
  }
  printf("Len = %d\n",i);
  printf("Total alphabets = %d upper alphabets = %d lower alphabets = %d\n",a,ua,la);
  printf("digits = %d  spaces = %d special characters = %d\n",d,sp,spl);
	
}
int main()
{
  char n[20];
  printf("Enter any string ");
  gets(n);
  show(n);
  return(0);
}
