C program to find the length of a string without strlen() function

Problem Statement:

C program to count the number of vowels, consonants, spaces and digits in a sentence.

Logic :

• The program  took a string sentence from the user.
• At first, the variables vowels, consonants, number and spaces are initialized to 0. 
• Within a  for loop  we check for  vowels, consonants, number and spaces and when found we increment the corresponding variable by 1.
• At last, we are printing the corresponding count on the screen.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

#include #include #include #define SIZE 100 //size of the string void main() { char sentence[SIZE],ch; int i; int vowels=0,consonants=0,number=0,spaces=0; printf("Enter the sentance \n"); gets(sentence); for(i=0; i<strlen(sentence); i++) { if(sentence[i]=='A' || sentence[i]=='a' || sentence[i]=='E' || sentence[i]=='e' || sentence[i]=='I' || sentence[i]=='i' || sentence[i]=='O' || sentence[i]=='o' || sentence[i]=='U' || sentence[i]=='u') { vowels++; } else if((sentence[i]>='a' && sentence[i]<='z') || (sentence[i]>='A && sentence[i]<='Z')) { consonants++; } else if(sentence[i]>='0' && sentence[i]<='9') { number++; } else if (sentence[i]==' ') { spaces++; } } printf("The number of vowel is %d ,consonant is %d, number is %d and blank spaces is %d \n",vowels,consonants,number,spaces); }
