This is the simple implementation of the “Copy” function of the computer world. This program copies the content of one string to another.
Logic : The program asks the user to input the string to copy and stores this as str1. The inner function “stcpy” takes 2 strings as arguments. By keeping the length as the reference, it traces till EOL , for each i of this iteration, it copies the i-th letter to the destination string, i.e str2.
After the EOL, it puts a NULL to the second line. That gives the duplicated string of the entered.
#include<stdio.h>
#include<conio.h>
void stcpy(char str1[50], char str2[50]);
void main()
{
char str1[50], str2[50];
clrscr();
printf(“\n\n\t ENTER A STRING…: “);
gets(str1);
stcpy(str1,str2);
printf(“\n\t THE COPIED STRING IS…: “);
puts(str2);
getch();
}
void stcpy(char str1[50], char str2[50])
{
int i, len = 0;
while(str1[len]!=’\0′)
len++;
for(i=0;i<len;i++)
str2[i] = str1[i];
str2[i] = ‘\0′;
}

mujhe koi ye program smjha do,means every step kaise kaise ho rha ek array box example me le k plz plz!
Q-wap input a string then find out occurence of each character?
void main()
{
int i ,j,k,c;
printf(“enter a string”);
gets(a);
for(i=0;i<strlen(a);i++)
{
c=1;
for(j=i+1;j<strlen(a);j++)
{
c++;
for(k=j;k<strlen(a);k++)
a[k]=a[k+1];
j–;
}
}
printf("\n%c=%dtimes",a[i],c);
}
getch();
}
