Question

int truncate(char str[], unsigned int index);

Create a function called truncate() that takes a string and integer as a parameter. Your function should truncate the string by placing a NULL byte at the specified index. You should return the index passed as a parameter if successful, -1 on fail. For example, if the index given is 5, but the string is “fun”, you would return -1 because the string is not long enough.

#source code in c language:

#include <stdio.h>

int truncate(char str[], unsigned int index);

int main(){

printf("%d\n",truncate("fun",5));

return 0;

}

int truncate(char str[], unsigned int index){

for(int j=0;j<str[j]!='\0';j++){

if(j==index){

return index;

}

}

return -1;

}
