C Program To Copy One String To Another String using For Loop
#include <stdio.h>
int main()
{
char s1[1000],s2[1000];
int i;
printf("Enter any string: ");
gets(s1);
for(i=0;s1[i]!='#include <stdio.h>
int main()
{
char s1[1000],s2[1000];
int i;
printf("Enter any string: ");
gets(s1);
for(i=0;s1[i]!='\0';i++) // or for(i=0;s1[i];i++)
{
s2[i]=s1[i];
}
s2[i]='\0';
printf("original string s1='%s'\n",s1);
printf("copied string s2='%s'",s2);
return 0;
}';i++) // or for(i=0;s1[i];i++)
{
s2[i]=s1[i];
}
s2[i]='#include <stdio.h>
int main()
{
char s1[1000],s2[1000];
int i;
printf("Enter any string: ");
gets(s1);
for(i=0;s1[i]!='\0';i++) // or for(i=0;s1[i];i++)
{
s2[i]=s1[i];
}
s2[i]='\0';
printf("original string s1='%s'\n",s1);
printf("copied string s2='%s'",s2);
return 0;
}';
printf("original string s1='%s'\n",s1);
printf("copied string s2='%s'",s2);
return 0;
}
The output of the above c program; as follows:
Enter any string: tutsmake original string s1='tutsmake' copied string s2='tutsmake'
