IGNOU MCS-011-Problem Solving and Programming, Latest Solved Assignment (July 2023 - January 2024 )
Q4. Write interactive C programs to perform the following on strings:
(a) To find the length of a given string without using the string library functions.
(b) To compare two strings without using string library functions.
(c)To count the total number of vowels and consonants in a string and display the counts separately.
Ans. (a) To find the length of a given string without using the string library functions.
// C program to find length of the string without using strlen() function
#include <stdio.h>
int main()
{
char s[100];
int i;
printf(“Enter a string: “);
scanf(“%s”, s);
for(i = 0; s[i] != ‘\0’; ++i);
printf(“Length of string: %d”, i);
return 0;
}
(b) To compare two strings without using string library functions.
#include <stdio.h>
#include <string.h>
int main()
{
char Str1[100], Str2[100];
int result, i;
printf(“\n Please Enter the First String : “);
gets(Str1);
printf(“\n Please Enter the Second String : “);
gets(Str2);
for(i = 0; Str1[i] == Str2[i] && Str1[i] == ‘\0’; i++);
if(Str1[i] < Str2[i])
{
printf(“\n str1 is Less than str2”);
}
else if(Str1[i] > Str2[i])
{
printf(“\n str2 is Less than str1”);
}
else {
printf(“\n str1 is Equal to str2”);
}
return 0;
}
(c) To count the total number of vowels and consonants in a string and display the counts separately.
#include <stdio.h>
#include <string.h>
#define MAX_SIZE 100 // Maximum string size
int main()
{
char str[MAX_SIZE];
int i, len, vowel, consonant;
/* Input string from user */
printf(“Enter any string: “);
gets(str);
vowel = 0;
consonant = 0;
len = strlen(str);
for(i=0; i<len; i++)
{
if((str[i]>=’a’ && str[i]<=’z’) || (str[i]>=’A’ && str[i]<=’Z’))
{
if(str[i] ==’a’ || str[i]==’e’ || str[i]==’i’ || str[i]==’o’ || str[i]==’u’ || str[i] ==’A’ || str[i]==’E’ || str[i]==’I’ || str[i]==’O’ || str[i]==’U’ )
vowel++;
else
consonant++;
}
}
printf(“Total number of vowel = %d\n”, vowel);
printf(“Total number of consonant = %d\n”, consonant);
return 0;
}
