Question

Write the following program in C Language using standard library functions.

/*Implement the Find function, called in the program below. This function receives two strings, and looks for the first occurrence of the second string in the first string, returning the number of characters it is in, relative to the beginning of the first string. If not, returns -1. In the program, a string with two news headlines is given, and the sub-strings "iPad" and "Huawei” are searched for, having found both substrings as can be confirmed in the example execution*/ //Program: #include <stdlib.h> int main() { char *str = "Huawei Mate 30 Pro with super, super, super Slow Motion. \ Next iPad Pro may include triple camera."; printf("\n Text contains 'iPad' in position %d and 'Huawei' in position %d.", Find (str, "iPad"), Find (str, "Huawei")); } //Example execution: // C: \ -..> feature192092 // Text contains 'iPad' at position 64 and 'Huawei' at position 0.

PROGRAM::

#include <stdio.h>
int find(char *src, char *str) {
int i, j, firstOcc;
i = 0, j = 0;

while (src[i] != '\0') {

while (src[i] != str[0] && src[i] != '\0')
i++;

if (src[i] == '\0')
return (-1);

firstOcc = i;

while (src[i] == str[j] && src[i] != '\0' && str[j] != '\0') {
i++;
j++;
}

if (str[j] == '\0')
return (firstOcc);
if (src[i] == '\0')
return (-1);

i = firstOcc + 1;
j = 0;
}
}
int main()
{
char *str = "Huawei Mate 30 Pro with super, super, super Slow Motion. \
Next iPad Pro may include triple camera.";
printf("\n Text contais 'iPad' at position %d and 'Huawei' at position %d", find(str,"iPad"),find(str, "Huawei"));

return 0;
}
SCREENSHOTS::

int find(char *src, char *str) { int i, j, firstocc; i = 0, j = 0; while (src[i] != '\0') { while (src[i] != str[@] && src[i] != '\0') i++; if (src[i] == '\0') return (-1); firstocc = i; str[j] && src[i] != '\0' && str[j] != '\0') { while (src[i] i++; j++; ہ == if (str[j] 10') return (firstocc); if (src[i] '10') return (-1); i = firstocc + 1; j = 0; ہ } int main() char *str = "Huawei Mate 30 Pro with super, super, super Slow Motion. Next iPad Pro may include triple camera."; printf("\n Text contais 'iPad' at position %d and 'Huawei' at position %d", find(str, "iPad"), find(str, "Huawei")); return 0;
