Write a C program that uses functions to perform the following operations:

i. To insert a substring into a given main string from a given position.

ii. To delete n characters from a given position in a given string.

Program Code i:

#include <stdio.h>

#include <string.h>

int main() {

int i,j,p,s1=0,s2=0,tem=0;

char str1[100],str2[100],temp[100];

printf("Enter the first string : ");

gets(str1);

printf("Enter the second string : ");

gets(str2);

printf("Enter the position to insert the second string : ");

scanf("%d",&p);

for(i=0;str1[i]!='\0';i++)

{

s1++;

}

for(i=0;str2[i]!='\0';i++)

{

s1++;

}

for(i=0;temp[i]!='\0';i++)

{

tem++;

}

j=0;

for(i=p;i<s1;i++)

{

temp[j] = str1[i];

j++;

}

str1[p] = '\0';

j=0;

for(i=p;i<(s1+s2);i++)

{

str1[i] = str2[j];

j++;

}

strcat(str1,temp);

puts(str1);

}

Program Code ii:

#include <stdio.h>

int main() {

int i,p,j,s1=0,n;

charstr[100],temp[100];

printf("Enter the string : ");

gets(str);

printf("Enter the position : ");

scanf("%d",&p);

printf("Enter the number of characters you want to delete : ");

scanf("%d",&n);

for(i=0;str[i]!='\0';i++) 

{

s1++;

}

j=0;

for(i=p+n;i<s1;i++) 

{

temp[j] = str[i];

j++;

}

str[p] = '\0';

j=0;

for(i=p;i<s1-p+n;i++) 

{

str[i] = temp[j];

j++;

}

puts(str);

}
