C Program to count vowels, digits, spaces, consonants using the string concepts
An array of characters (or) collection of characters is called a string.
Declaration
Refer the declaration given below −
char stringname [size];
For example − char a[50]; string of length 50 characters.
Initialization
The initialization is as follows −
- Using single character constant −
char a[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}- Using string constants −
char a[10] = "Hello":;
Accessing
There is a control string “%s” used for accessing the string, till it encounters ‘\0’.
The logic used to count number of vowels is as follows −
if(string[i]=='a'||string[i]=='e'||string[i]=='i'|| string[i]=='o'||string[i]=='u')//checking the char is vowel vowel=vowel+1;
The logic used to count number of digits is as follows −
if(string[i]=='0'||string[i]=='1'||string[i]=='2'|| string[i]=='3'||string[i]=='4'||string[i]=='5'|| string[i]=='6'||string[i]=='7'||string[i]=='8'||string[i]=='9') digit=digit+1;
The logic used to count number of spaces is as follows −
if(string[i]==' ') space=space+1;
Else, remaining all consonants.
Program
Following is the C Program to count vowels, digits, spaces, consonants by using the string concepts −
#include<stdio.h>
int main(){
char string[50];
int i,vowel=0,digit=0,space=0,consonant=0;
printf("enter any string includes all types of characters:
");
gets(string);
for(i=0;string[i]!='\0';i++){
if(string[i]=='a'||string[i]=='e'||string[i]=='i'||
string[i]=='o'||string[i]=='u')//checking the char is vowel vowel=vowel+1;
else if(string[i]=='0'||string[i]=='1'||string[i]=='2'||
string[i]=='3'||string[i]=='4'||string[i]=='5'||
string[i]=='6'||string[i]=='7'||string[i]=='8'||string[i]=='9')
digit=digit+1;
else if(string[i]==' ')
space=space+1;
else
consonant=consonant+1;
}
printf("vowel=%d
digit=%d
space=%d
consonant=%d
",vowel,digit,space,consonant);
return 0;
}Output
The output is given below −
