Using pointers, write a program in ‘C’ to count the occurrence of each character in a given string. 10m Dec2006 #include <stdio.h> #include <string.h> void main() { char string[100],*ptr; int c=0,count[26]={0}; clrscr(); printf(“Enter a string\n”); gets(string); ptr=string[0]; while (*ptr) { /* Consider characters from ‘a’ to ‘z’ only */ if ( ptr >= ‘a’… Read More »
Write a program in ‘C’ to find the length of a given string including blank spaces, tabs and other special symbols (new line character should be taken as a string terminating character) Note : You should use “Pointers” concept. 10m Dec2005 Use while(str[i] != “\n”) instead of while(*str) Solved program can be found… Read More »
Let’s identify variables needed for this program. In this program, we need several variables to store string and count the number of characters in the given string. First variables will be the one which will save the string entered by the user and reverse of it. So it will be S[50] and R[50]. In C… Read More »
