gets(str);
printf(“enter the string to be replaced... \n”);
gets(str1);
printf(“enter the replacing string...);
gets(str2);
printf(“\n the replaced line of the text....);
while(1)
{
ptr=strstr(str,str1);
if(ptr==?\o?)
break;
cnt=ptr-str;
strncpy(temp,str,cnt);
temp[cnt]=?10?;
strcat(temp,str+cnt+strlen(srt1));
